Searching for new sources of matter–antimatter symmetry breaking in Higgs boson interaction with top quarks
When a particle is transformed into its antiparticle and its spatial coordinates inverted, the laws of physics are required to stay the same—or so we thought. This symmetry—known as CP symmetry (charge conjugation and ...

Gravitational waves could prove the existence of the quark-gluon plasma
Neutron stars are among the densest objects in the Uiverse. If our Sun, with its radius of 700,000 kilometres were a neutron star, its mass would be condensed into an almost perfect sphere with a radius of around 12 kilometres. ...

New LHCb analysis still sees previous intriguing results
At a seminar today at CERN, the LHCb collaboration presented a new analysis of data from a specific transformation, or "decay," that a particle called B0 meson can undergo. The analysis is based on twice as many B0 decays ...

3-D imaging the flavor content of the nucleon
The Jefferson Lab Hall A Collaboration, in an experiment led by researchers at Faculté des Sciences de Monastir in Tunisia, Institut de Physique Nucléaire d'Orsay in France and Old Dominion University in the United States, ...
Exploring strangeness and the primordial Universe
Physicists believe that in the Universe's first ten microseconds free quarks and gluons filled all of spacetime, forming a new phase of matter named 'quark-gluon plasma' (QGP). Experimental and theoretical work at CERN was ...

Leptons help in tracking new physics
Electrons with 'colleagues'—other leptons—are one of many products of collisions observed in the LHCb experiment at the Large Hadron Collider. According to theorists, some of these particles may be created in processes ...

Deuteron-like heavy dibaryons—a step towards finding exotic nuclei
Have you ever wondered how the Sun creates the energy that we get from it every day and how the other elements beside hydrogen have formed in our universe? Perhaps you know that this is due to fusion reactions where four ...

Physicists measure the variation of the top-quark mass for the first time
For the first time, CMS physicists have investigated an effect called the "running" of the top quark mass, a fundamental quantum effect predicted by the Standard Model.
