The BESIII collaboration has reported the most precise measurements to date of the relative strong-phase parameters in decays of neutral D mesons. These results are presented in two articles published ...

The study of hadrons—particles that combine quarks to form mesons or baryons—is a vital part of the physics programme by researchers of the ATLAS Experiment at CERN. Their analysis has not only ...

Smashing protons together in search of strange particles, scientists at the Large Hadron Collider near Geneva say they’ve discovered signs of particle decays that have long been predicted, but have ...

The LHCb experiment at CERN has observed a rare decay of the B meson. (Courtesy: Maximilien Brice / CERN) The rare decay of a neutral B meson to two oppositely charged kaons has been observed for the ...

Cracow, 12 April 2017 All physical theories are to a greater or lesser extent, but always only simplified representations of reality and, as a consequence, have a specified range of applicability.

It’s a story with a hint of both “man bites dog” and “dog bites man” about it. Physicists working on the CMS and LHCb experiments at CERN have independently seen an incredibly rare decay of a particle ...

There were a huge variety of potential new physics signatures that physicists have been seeking at the LHC, from extra dimensions to dark matter to supersymmetric particles to micro-black holes. But ...

Amid the chaotic chains of events that ensue when protons smash together at the Large Hadron Collider in Europe, one particle has popped up that appears to go to pieces in a peculiar way. All eyes are ...

A scientist stands in front of pictures of the first successful collisions at full power at the CMS experience control room of the LHC at the CERN in Meyrin. Science's 2011 Watch list to focus on ...

For the first time, scientists at CERN have observed extremely rare leftovers from subatomic particles. The observations support a fundamental theory of particle physics, according to a paper ...

Physicists have for the first time pinned down one of the rarest particle transformations glimpsed – the decay of a B s meson into a muon and its antiparticle. The sighting might not spark celebration ...
