Physicists have found a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science...
Top-quark pair production has been observed in lead-lead collisions at CERN’s Large Hadron Collider (LHC) with the ATLAS detector, marking the first...
Since its discovery 20 years ago physicists have been fascinated by χc1(3872), which is also known as X(3872), trying to understand if it is a conventional...
Physicists with the BESIII Collaboration have observed an anomalous line shape around ppbar mass threshold in the J/ψ→γ3(π+π-) decay, which indicates...
Physicists from the LHCb Collaboration at CERN’s Large Hadron Collider (LHC) have reported the first observation of the decay of the Bc+ meson (composed...
The proton is one of the main building blocks of all visible matter in the Universe. Among its intrinsic properties are its electric charge, mass and spin....
The physics of the gravitational form factors of the proton, as well as their understanding within quantum chromodynamics, has advanced significantly in...
Neutron-star cores contain matter at the highest densities in our Universe. This highly compressed matter may undergo a phase transition where nuclear...
Physicists from the STAR Collaboration at the Relativistic Heavy Ion Collider, an atom smasher at Brookhaven National Laboratory, have tracked pairs of...
Nuclear matter is a hypothetic substance consisting of interacting quarks and gluons in large enough numbers that the system can be considered infinite.
Left:...
Though widely thought to be a fluke when seen in earlier measurements, the new, more precise measurement has confirmed the presence of the anomaly and...
Physicists from the ALICE Collaboration at CERN’s Large Hadron Collider have precisely measured two properties of hypernuclei that may exist in the cores...
The strong force, also referred to as the strong nuclear force, is one of the four basic forces in nature, along with gravity, the electromagnetic force,...
Physicists from the Large Hadron Collider beauty (LHCb) Collaboration at CERN’s Large Hadron Collider (LHC) announced today the observation of a strange...
In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution...
Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider (LHC) have substantially improved the precision with which...
Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider have detected about 100 particles of a type known as X(3872)...
The new exotic particle discovered by physicists from the LHCb Collaboration at CERN’s Large Hadron Collider (LHC) contains two quarks and two antiquarks....
Quark-gluon plasma is a state of dense matter with the quarks and gluons being its constituents. Soon after the Big Bang the matter was just in such a...
Physicists from the LHCb Collaboration at CERN’s Large Hadron Collider (LHC) have observed four new exotic particles: Zcs(4000)+, Zcs(4220)+, X(4685),...
