E. Cortina, A. Kleimenova, E. Minucci, S. Padolski et autres

Searches for lepton number violating K + → π − e + e + and K + → π − π 0 e + e + decays have been performed using the complete dataset collected by the NA62 experiment at CERN in …

Search for K+ decays to a lepton and invisible particles

N. Lurkin, A. Akmete, R. Aliberti, F. Ambrosino et autres

Searches for heavy neutral leptons $N$ in the $K^+\to e^+N$ and $K^+\to \mu^+N$ decay channels using the dataset collected by the NA62 experiment at CERN between 2016-2018 are presented. Upper limits on the corresponding mixing matrix elements are reported at the level …

ChPT tests at the NA48 and NA62 experiments at CERN

Na Collaborations, F. Ambrosino, A. Antonelli, G. Anzivino et autres

The NA48/2 Collaboration at CERN has accumulated unprecedented statistics of rare kaon decays in the Ke4 modes: Ke4(+-) ($K^\pm \to \pi^+ \pi^- e^\pm \nu$) and Ke4(00) ($K^\pm \to \pi^0 \pi^0 e^\pm \nu$) with nearly one percent background contamination. The detailed study of …
