Inicia sesión para fijar este evento

El experimento LHCb del CERN informó sobre la evidencia de una desintegración ultra-rara del mesón B⁰ en dos muones, con una significancia estadística de 3,2 σ. En informes anteriores, la colaboración presentó datos que indicaban una desintegración rara del mesón Bd en un par de muones con la misma significancia. Estudios previos habían demostrado que la tasa observada del decaimiento B⁰ concuerda con las predicciones del Modelo Estándar.

La medición fue posible gracias a un detector mejorado desarrollado por investigadores de la Universidad de Liverpool. Estos hallazgos se suman a investigaciones del CERN que exploran interacciones de partículas a escalas cien mil millones de veces menores que un átomo.
