To obtain these new results of the CP asymmetry in the disintegration process of the B s 0 meson, data collected by the LHCb experiment during Run 2 were combined with previous decay data of this type and other related ones obtaining, in a single experiment, the most precise single measurements of these quantities to date, consistent with expectations based on the Standard Model and with a previous LHCb analysis.

The most accurate and consistent analysis with the Standard Model However, some still unknown phenomenon had to happen so that the first one prevailed, forming the atoms that compose everything that exists around us. If both were created at the beginning of the universe with the same properties, except for their electric charge, they should have been annihilated. During this process, there is an asymmetry in the behavior of some unstable quarks, the CP violation, which would explain the observed discrepancy between matter and antimatter. By measuring their transformation properties, frequency and phase, new aspects about the composition of the Higgs field may be revealed. This kind of “ticking”, motivated by the interaction of these hadrons with the Higgs field, continues until they decay.

The B s 0 meson is a particle composed mainly of two quarks -b, bottom and s, strange- that spontaneously transforms into its own antiparticle and then returns to become an in B s 0 meson. These measurements, coordinated by the researcher of the Galician Institute of High Energy Physics (IGFAE) and professor of the USC Veronika Chobanova and Francesca Dordei of the National Institute of Nuclear Physics (INFN), also represent the last step before analysing all the of LHCb dataset. The LHCb collaboration, one of the seven experiments at the LHC (Large Hadron Collider) at CERN, sent new results to the European Physics Journal C on June 21 that could provide new clues to clarify the origin and composition of dark matter and why matter prevailed over antimatter after the Big Bang: the most accurate analysis of a CP asymmetry phase in the B s 0 meson decay.
