Exploration with LHCb: from unseen to rare
Exploration with LHCb: from unseen to rare Flavour physics, even at low-energy scales, offers a glimpse at energy scales far higher than those reachable directly thanks to the quantum loop effects, which are present in the quark transitions. The rarer or more suppressed a given transition is within the standard model (SM) of particle physics,

New precise measurements of CP violation and mixing in beauty and charm decays at LHCb
New precise measurements of CP violation and mixing in beauty and charm decays at LHCb In 1928, a young Paul Dirac wrote one of the most spectacular papers of modern physics when he successfully unified two distinct theories, quantum mechanics and special relativity. What arose from his equations was a prediction of a new form

LHCb in the hunt of tetraquarks
LHCb in the hunt of tetraquarks In 2003, the Belle collaboration reported the observation of an unexpected new particle, showing up in the mass spectrum of J/ψ π π candidated. Its mass was somewhat close to the value expected for the yet unobserved χc1(2P) charmonium, but its width was extremely narrow and completely dominated by

LHCb observes CP violation in charm
LHCb observes CP violation in charm We live in a Universe of matter, which is a good thing but poses a problem: We know that in the Big Bang initially as much matter as antimatter was produced, and that the antimatter somehow disappeared. How this happened is one of the questions that the LHCb experiment
