This quantity can be used to put constraints on contributions from processes beyond the Standard Model in the B0 s meson system and is determined by two complementary approaches as8 p.application/pdfengcc by (c) Ruiz, Hugo (Ruiz Pérez) et al., 2012http://creativecommons.org/licenses/by/3.0/es/Física de partículesExperimentsGran Col·lisionador d'HadronsParticle physicsExperimentsLarge Hadron Collider (France and Switzerland)Measurement of the effective B-S(0) -> K+K- lifetimeinfo:eu-repo/semantics/article6058012023-03-21info:eu-repo/semantics/openAccess
