B meson - Wikipedia
WEBIn particle physics, B mesons are mesons composed of a bottom antiquark and either an up ( B+. ), down ( B0. ), strange ( B0. s) or charm quark ( B+. c). The combination of a bottom antiquark and a top quark is not thought to …
The B Meson - HyperPhysics
WEBThe B Meson. The B-meson contains a b-quark and the least massive variety has a mass about 5.6 times that of a proton. The table summarizes the properties of the B variety which contains the b-quark along with an up or down quark.
Unexplained Results Intrigue Physicists at World's Largest …
WEBMar 25, 2021 · Specifically, scientists are interested in fresh data from the LHCb (Large Hadron Collider beauty) detector, an experiment studying the decays of B-mesons—particles that contain beauty quarks.
Largest matter-antimatter asymmetry observed - CERN
WEBMar 18, 2022 · One spectacular result of such an analysis is the indication of a χhc0 meson (containing a charm-anticharm quark pair) being formed during the B→πππ decay. The χhc0 was not expected to contribute to CP violation but the results show the presence of a significant asymmetry.
B meson decays | PMC Physics A | Full Text
WEBFeb 20, 2009 · We discuss the most important Physics thus far extracted from studies of B meson decays. Measurements of the four CP violating angles accessible in B decay are reviewed as well as direct CP violation.
Strange B meson - Wikipedia
WEBStrange B mesons are noted for their ability to oscillate between matter and antimatter via a box-diagram with Δm s = 17.77 ± 0.10 (stat) ± 0.07 (syst) ps −1 measured by CDF experiment at Fermilab. [1] That is, a meson composed of a bottom quark and strange antiquark, the strange B meson, can spontaneously change into an bottom antiquark and strange quark pair, the strange
New study of rare B meson decays to two muons | CMS …
WEBJul 11, 2022 · One of such processes is the rare decay of neutral B mesons to a muon-antimuon pair, μ + μ-. There are two types of such B mesons: the B 0 meson that consists of a bottom antiquark and a down quark, while for the B s meson the down quark is replaced by a strange quark.
WEBich we scrutinize in this paper. We study CP violating observables in the B0 q B0 q system, discuss current and expected sensitivities for the exotic decays of B mesons into a visible baryon and missing energy, and explore the implications of direct searches for a TeV-scale colored scalar at the LHC.
Physics - Analysis Finds <i>B</i> Meson Behaves Itself
WEBJan 25, 2022 · The researchers found that the strange B meson, which consists of a bottom antiquark and a strange quark, decays into a pair of muons three times every billion decays, consistent with their previous measurement.
b-meson - CERN
WEBUsing LHC Run 2 data, CMS has precisely measured the rare decay of strange B-mesons to muon-antimuon pairs. While its properties agree with Standard Model predictions, it may provide clues to new discoveries in Run 3. News.
