Observation of several sources of $C P$ violation in $B^{+} \to K^{+} π^{+} π^{-}$ decays

LHCb collaboration, R. Aaij, M. Abdelfatah +1116

An amplitude analysis of $B^{+} \to K^{+} π^{+} π^{-}$ decays is presented in which six $C P$ -violating phenomena are judged to be of significance for the first time. This analysis is b…

Reactor-based Search for Axion-Like Particles using CsI(Tl) Detector

S. Sahoo, S. Verma, M. Mirzakhani +5

The absence of conclusive signals in weakly interacting massive particle (WIMP) searches has motivated increased interest in alternative dark matter candidates such as axions and a…
