Observation of the K⁺rightarrowπ⁺νbar{ν} decay and measurement of its branching ratio
read the original abstract
A measurement of the $K^{+}\rightarrow\pi^{+}\nu\bar{\nu}$ decay by the NA62 experiment at the CERN SPS is presented, using data collected in 2021 and 2022. This dataset was recorded, after modifications to the beamline and detectors, at a higher instantaneous beam intensity with respect to the 2016--2018 data taking. Combining NA62 data collected in 2016--2022, a measurement of $B(K^{+}\rightarrow\pi^{+}\nu\bar{\nu}) = \left( 13.0^{+ 3.3}_{- 3.0} \right)\times10^{-11}$ is reported. With $51$ signal candidates observed and an expected background of $18^{+3}_{-2}$ events, $B(K^{+}\rightarrow\pi^{+}\nu\bar{\nu})$ becomes the smallest branching ratio measured with a signal significance above $5\,\sigma$.

Irreducible Constraints on Hadronically Interacting Sub-GeV Dark Matter
Sub-GeV dark matter that interacts hadronically is ruled out for nucleon scattering cross sections above 10^{-36} cm² across the keV to 100 MeV mass range by combined cosmological and particle-decay constraints.

CP violation in $K\to\mu^+\mu^-$ with and without time dependence through a tagged analysis
Combined time-integrated CP asymmetry A_CP and B(K_S to mu mu) measurements, using known B(K_L to mu mu) and B(K_L to gamma gamma), extract the short-distance amplitude |A^2 lambda^5 eta-bar| and resolve the discrete ...

Revisiting $\mu$-$e$ conversion in $R$-parity violating SUSY
RG running changes limits on certain RPV SUSY λ and λ' couplings by up to 80 percent, with upcoming μ-e conversion experiments expected to set stronger bounds than μ→eγ or μ→eee decays.
