LHCb observes a new decay mode of the charmed beauty meson

The LHCb collaboration recently reported on the arXiv preprint server the first observation of the decay of the Bc+ meson (composed of two heavy quarks, b and c) into a J/ψ charm-anticharm quark bound state and a pair of ...

The standard model of particle physics may be broken, expert says

As a physicist working at the Large Hadron Collider (LHC) at Cern, one of the most frequent questions I am asked is "When are you going to find something?" Resisting the temptation to sarcastically reply "Aside from the Higgs ...

Weak-value-based metrology surpasses classical limit

(Phys.org)—When measuring very small physical effects, such as the deflection of a light beam, the very act of measuring can affect the measurement outcome. Now in a new study, physicists have experimentally demonstrated ...

High-precision magnetic field sensing

Scientists have developed a highly sensitive sensor to detect tiny changes in strong magnetic fields. The sensor may find widespread use in medicine and other areas.

Are weak values quantum? Don't bet on it

(Phys.org) —New work asserts that a key technique used to probe quantum systems may not be so quantum after all, according to Perimeter postdoctoral researcher Joshua Combes and his colleague Christopher Ferrie.
