Calibration of the ATLAS calorimeters and discovery potential for massive top the central calorimeters of ATLAS and outlines a search for heavy top quark pair

The physicist who discovered it, Murray Gell-Mann, loves words as much as he loves physics. He is known to correct a stranger’s pronunciation of his or her own last name (which doesn’t always go over well) and is more than happy to give names to objects or ideas that do not have one yet. Thus came the word quark for his most famous discovery.

S quark discovery

The particle, named Pc(4312)+, decays to a proton and a J/ψ particle (composed of a charm quark and an anticharm quark). This latest observation has a statistical significance of 7.3 sigma, passing the threshold of 5 sigma traditionally required to claim a discovery of a new particle. In the conventional quark discovery of the top quark at CERN was imminent. Finding it would still be a difﬁcult feat. When protons and antipr otons hit one another at high ener gies, the actual collision is between their inter nal quarks and gluons. Each quark or gluon car-ries just a modest fraction of the total energy of its host pr oton or antipr oton, It is the last undiscovered particle in the Standard Model's bestiary. A precise mass for the top quark will help theorists constrain the Higgs mass, improving its chances of detection at Fermilab or the LHC in the next decade.

Strange quarks are found in subatomic particles called hadrons. Examples of hadrons containing strange quarks include kaons, strange D mesons, Sigma baryons, and other strange particles.

Creating top-antitop pairs in sufficient numbers to claim discovery demanded Both groups found events in which one or both W s decayed into an electron or

G. By the mid-1960's, physicists realized that their previous understanding, where all matter is composed of the fundamental protons, neutrons, and electron, was insufficient to explain the myriad new particles being discovered. Gell-Mann's and Zweig's quark theory solved these problems. The LHCb collaboration has observed a type of four-quark particle never seen before. The discovery, presented at a recent seminar at CERN and described in a paper published today is likely to be The new particle, a class of “tetraquark,” is made of a bottom quark, a strange quark, an up quark and a down quark.
