An elusive particle that first formed in the hot, dense maelstrom of the early universe has puzzled physicists for decades.

So-called “XYZ states” defy the standard picture of particle behavior and have given rise to several attempts to understand ...

Gravity, however, is not included. This theory organizes particles into two main categories: quarks and leptons. Quarks form protons and neutrons, while leptons include particles such as electrons and ...

researchers significantly improved by measuring how often top-quark pairs are produced alongside jets from charm quarks (c-jets) for the first time. They analyzed events with one or two leptons ...

broke new ground by providing the first dedicated ATLAS measurement of how often top-quark pairs are produced along with jets originating from charm quarks (c-jets). ATLAS physicists analysed events ...

ABSTRACT: The massive vector bosons Z o, W ± and the scalar Higgs-boson H o assumed in weak interaction theory, but also the six quarks required in strong interactions are well understood in an ...

The LHCb produces sub-atomic particles called "beauty quarks", which are not usually found in nature but are produced at the LHC. Sub-atomic particles undergo a process known as decay, where one ...
