First observation of photons-to-taus in proton–proton collisions

In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in proton–proton collisions, which ...

Study clarifies a key question in particle physics about muon's magnetic moment

Magnetic moment is an intrinsic property of a particle with spin, arising from interaction between the particle and a magnet or other object with a magnetic field. Like mass and electric charge, magnetic moment is one of ...

Cracking the quantum code: Simulations track entangled quarks

Today, the word "quantum" is everywhere—in company names, movie titles, even theaters. But at its core, the concept of a quantum—the tiniest, discrete amount of something—was first developed to explain the behavior ...

LHCb finds bottom quarks are more likely to exist in baryons than mesons as the environment density increases

The team of physicists working on the LHCb Collaboration at CERN has found that bottom quarks are more likely to exist in baryons than mesons as the density of the environment in which they exist increases. In their paper ...

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 ...

How 'the strong force' influences the gravitational wave background

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.
