La colaboración LHCb del CERN anunció que ha observado evidencia de una desintegración ultra-rara de una partícula beauty que ocurre en aproximadamente una de cada diez mil millones de casos, ofreciendo una nueva prueba del Modelo Estándar y una ventana a la llamada Zeptoverso. Anteriormente, Sci. News informó que la tasa medida de desintegración de mesones B0 en pares de muones concuerda con las predicciones del Modelo Estándar.

Mirage News señaló que el hallazgo fue posible gracias a un detector mejorado desarrollado por investigadores de la Universidad de Liverpool. BBC había destacado que los físicos del CERN están investigando interacciones a escalas cien mil millones de veces menores que un átomo, mostrando la capacidad del experimento para explorar fuerzas fundamentales.
