Scientists at the Large Hadron Collider in Switzerland have discovered one new pentaquark and two tetraquarks. This takes the total number discovered there ...

The new pentaquark decays into particles that none of the others produces, while the two tetraquarks have the same mass, suggesting they may be the first known pair of exotic structures, as reported by BBC. Physicists hope the resumption of collisions will help in their quest for so-called "dark matter" that lies beyond the visible universe. Scientists at CERN, the European Organization for Nuclear Research will this week fire up the 27-kilometre-long Large Hadron Collider (LHC), the machine that found the Higgs boson particle, after a shutdown for maintenance and upgrades was prolonged by COVID-19 delays.

Their focus remains the Higgs boson. Andreas Hoecker, spokesman of the Atlas collaboration, said: “We will measure the strengths of the Higgs boson interactions with matter and force particles to unprecedented precision, and we will further our searches for Higgs boson decays to dark matter particles as well as searches for additional Higgs bosons.” During the experiments, scientists will look at the nature of the Higgs boson, discovered by the LHC ten years ago, with unprecedented precision and in new channels.

As for what CERN is actually doing, Andreas Hoecker, spokesperson of CERN’s ATLAS collaboration states on their website that “scientists will study the properties of matter under extreme temperature and density. It didn’t take long before many were convinced that on July 5th when CERN turns on their collider, the world would witness either the creation of a black hole or the opening of a portal to another dimension. The July 5th ignition of CERN’s Large Hadron Collider is no different, as a fake report which detailed an alleged black hole accident recently made the rounds.

CERN lights up the Large Hadron Collider for Run 3, a four year continuous run after its second long shutdown in 2018.

The beams collide in the machine at four points or "detectors" called ATLAS, CMS, ALICE and LGCb, each of which focusses on measuring different types of hadron particles. "We're looking forward to measurements of the Higgs boson decay to second-generation particles such as muons. Hence the need for accelerator like LHC with its 27km circumference, which accelerates hadron particles (such as lead, xenon and oxygen ions at different levels of the mass spectrum) in a way that forms two beams traveling in opposite directions, almost at the speed of light.

Upgrades to the colossal accelerator could help scientists discover new particles and gain better understanding of dark matter.

"In addition to the new hardware, ATLAS upgraded large parts of its software, simulation and computing environment to boost performance, save resources and enable it for use with heterogeneous computing systems," concludes Andreas. Of course, a centrepiece of the ATLAS physics programme remains the Higgs boson. These are but a few of the scientific highlights expected from Run 3. If it is made of particles, as most physicists expect, these may interact with protons or the Higgs boson and be produced in LHC collisions.” Dark matter is invisible and can only be spotted when produced with other, visible particles. The return of LHC beams comes after more than three years of upgrade and maintenance work, with new detector systems and electronic infrastructure installed 100 metres underground in the ATLAS cavern. We have prepared a broad scientific programme, taking advantage of new upgrades to our experiment."

On the other hand, it played a key role in the first moments after the Big Bang, this Boson has a long story to tell us. Particle physics is describing the infinitely small and what happens inside the fundamental building blocks that make up atoms such as elementary particles: electrons, photons, quarks, bosons and the forces with which they interact. CERN is making a fundamental contribution to the understanding of the laws that governed the functioning of the Universe in the first moments of life.

Data from the collisions is snapped up by high-tech detectors along the circular path. Most exotic hadrons, which are subatomic particles, are made up of two or three elemental particles known as quarks. The strong force is one of four forces known in the universe, along with the “weak force” — which applies to the decay of particles — as well as the electromagnetic force and gravity.

Data from the collisions is snapped up by high-tech detectors along the circular path. Most exotic hadrons, which are subatomic particles, are made up of two or three elemental particles known as quarks. The observation of a new type of pentaquark and the first duo of tetraquarks at CERN, the Geneva-area home to the Large Hadron Collider, offers a new angle to assess the “strong force” that holds together the nuclei of atoms.

It is the first pentaquark found to contain a strange quark. Observed in an analysis of decays of negatively charged B mesons, PΛψs(4338)0 is a pentaquark made up of a charm quark and a charm antiquark and an up, a down and a strange quark. In 2020, the LHCb physicists discovered a tetraquark made up of two charm quarks and two charm antiquarks, and two ‘open-charm’ tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark.

It is a pentaquark made up of a charm quark and a charm antiquark, and an up, a down, and a strange quark, CERN said. “The more analyses we perform, the more kinds of exotic hadrons we find,” LHCb physics coordinator Niels Tuning said. The second kind is a doubly electrically charged tetraquark.

It is a pentaquark made up of a charm quark and a charm antiquark, and an up, a down, and a strange quark, CERN said. “The more analyses we perform, the more kinds of exotic hadrons we find,” LHCb physics coordinator Niels Tuning said. The second kind is a doubly electrically charged tetraquark. Quarks are elementary particles that come in six “flavours”: up, down, charm, strange, top, and bottom. But they can also combine into four-quark and five-quark particles, called tetraquarks and pentaquarks. Two years ago, however, the LHCb experiment discovered an exotic tetraquark made up of two charm quarks and two charm antiquarks, and two “open-charm” tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark.

CERN scientists hailed a smooth start to what is expected to be nearly four years of operation in “Run 3” — the third time the LHC has carried out collisions since its debut in 2008. Most exotic hadrons, which are subatomic particles, are made up of two or three elemental particles known as quarks. Data from the collisions is snapped up by high-tech detectors along the circular path.

After a three-year shutdown, the Large Hadron Collider will smash particles together at the highest energies yet.

The LHC will run for four years, until collisions stop to make way for upgrades to an even more intensive machine. The particle beam has the power to damage detectors and machinery, so engineers will start cautiously, circulating only a minimum number of protons. Physicists will use the data deluge to learn more about the Higgs boson, which was discovered at CERN 10 years ago this week and about which myriad questions remain. Physicists upgraded the LHC experiments’ detectors, in particular improving their electronics and computing system to deal with the greater collision intensity. More-compact proton beams will allow the LHC to maintain a peak rate of collisions for longer, enabling experiments to collect more data in this run than in the previous two combined. A collision energy of 13.6 trillion electron volts (TeV), up from 13 TeV in the previous run, raises the probability of creating heavier and unknown particles (see ‘Data boost’). “With higher-energy data and a larger amount of data we can look further.

(In fact, the origin of the word "quark" goes back to a line from Finnegan's Wake by James Joyce: "Three quarks for Muster Mark!") Pions are two-quark combinations. CERN says this is the first time a pair of tetraquarks has been observed together. It's the first pentaquark known to include a strange quark. The three new types of subatomic particles, described today during a CERN seminar, aren't quite Higgs-level revelations. Gianotti said the LHC's scientists expect to collect as much data during this third run as they collected over the course of 13 years during the collider's previous two runs. The LHC had been shut down for three years to upgrade its systems to handle unprecedented energy levels.

It will also help to better understand conventional hadrons,” LHCb spokesperson Chris Parkes said. One is a pentaquark made up of a charm quark and a charm antiquark and an up, a down and a strange quark, which marks the first pentaquark found to contain a strange quark. We’re creating ‘particle zoo 2.0,” LHCb physics coordinator Niels Tuning said in a statement. In the last two years, researchers have discovered a tetraquark made up of two charm quarks and two charm antiquarks, and two “open-charm” tetraquarks consisting of a charm antiquark, an up quark, a down quark and a strange antiquark.
