Although the quark–gluon plasma at the LHC vanishes after about 10-23 s, scientists can study it by analysing how other particles produced in collisions move through it. The top quark is the heaviest ...
Top quarks are the heaviest of the six quark flavors, and are an especially valuable tool for studying the evolution of quark-gluon plasma. However, because they are the heaviest, their lifespan is ...
University of Glasgow physicists working on the ATLAS experiment at CERN have led a precise new measurement of the mass of the top quark, using high-transverse-momentum (‘boosted’) top quarks. The top ...
Nevertheless, mesons decay quite quickly, offering a crucial opportunity for symmetry to be broken. One paper reports on the decay of charged beauty mesons, composed of either a beauty quark and ...
Production and decay of anticharmed pentaquark state with quark content csudd. Journal: European Physical Journal C Published: 2025-01-20 DOI: ...
In superallowed decay, the nuclei lack spin making it easy to perform the required calculations. The framework revealed that measuring quark mixing has been challenging due to the various forces ...
The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their ...
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 of two heavy quarks, b and c) into a J/ψ ...
