Charged kaon
WebNov 10, 2024 · Meet the kaon. Nearly 75 years after the puzzling first detection of the kaon, scientists are still looking to the particle for hints of physics beyond their current … WebCurrent research on rare kaon decays focuses mostly on decays, which are predicted with good accuracy within the SM and beyond. Experimentally, these decays, especially that of the charged kaon, have a long history. Their theoretical importance is matched only by their experimental difficulty. This article reviews the progress of the past 10 ...

WebWe have studied the charged kaon ratio, spectra, rapidity densities, and inverse = slope parameter at mid-rapidity in Au+Au collisions at s NN 130GeV and = = s NN 200GeV … In particle physics, a kaon , also called a K meson and denoted K , is any of a group of four mesons distinguished by a quantum number called strangeness. In the quark model they are understood to be bound states of a strange quark (or antiquark) and an up or down antiquark (or quark). Kaons have proved to be a … See more The four kaons are : 1. K , negatively charged (containing a strange quark and an up antiquark) has mass 493.677±0.013 MeV and mean lifetime (1.2380±0.0020)×10 s. 2.

WebThis forces the charge conjugation of π0 to be ηC = +1. The spectra of charmonium ( c− ¯c bound states), or bottomonium ( b−¯b bound states) contain both positive and negative charge conjugation states. 20.3 CP Like parity, charge conjugation is conserved by the strong and electromagnetic interactions but not by the weak interactions, WebAug 1, 2010 · The Time Reversal Experiment with Kaons (TREK) at J-PARC aims to find New Physics beyond the Standard Model by measuring the T-violating transverse polarization PT of muons in the Kµ3+ decay of stopped kaons. TREK will use a high-intensity kaon beam and the upgraded apparatus of the E-246 experiment from KEK-PS.
WebFeb 19, 2024 · Meanwhile, CERN’s NA62 experiment announced finding no excess events for the equivalent decay of the positively charged kaon K + compared to predictions. Together, these results defy a well-established relationship between the rates of the two decays, which dictates that the K L decay should occur less frequently than its positively … WebThe unphysical charged pseudo-Goldstone bosons, which appear in other gauges, also have flavour- ... Charged Kaon decays had revealed in 1956 that Pand Care not conserved by the weak interaction, while physicists kept their faith in a good CP symmetry. If CP were conserved, we could assign CP quantum numbers to Klong and Kshort. The …
