Measurement of the branching ratio of the $K^+\to\pi^+\nu\bar{\nu}$ decay

Samuel Alibocus, B. Bloch-Devaux, Eduardo Cortina Gil, N. Lurkin et autres

The NA62 experiment has measured the branching ratio of the rare decay $K^+\to\pi^+\nu\bar{\nu}$ using data collected in 2023 and 2024 at the CERN SPS, obtaining $\mathcal{B}_{\rm 2023-2024}(K^+\to\pi^+\nu\bar{\nu}) = \left(7.2^{+2.3}_{-2.1}\right)\times10^{-11}$. With results from data collected between 2016 and 2022, the analysis gives $\mathcal{B}_{\rm …

Search for hadronic decays of feebly-interacting particles at NA62

Eduardo Cortina, J. Jerhot, N. Lurkin, T. Numao et autres

Abstract The NA62 experiment at CERN has the capability to collect data in a beam-dump mode, where 400 GeV protons are dumped on an absorber. In this configuration, New Physics particles, including dark photons, dark scalars, and axion-like particles, may be produced …

Experimental Study of Rare Kaon Decays at J-PARC with KOTO and KOTO II

J. K. Ahn, Emile Augustine, L. Bandiera, J. Bian et autres

The rare kaon decay $K_L\toπ^0ν\barν$ is extremely sensitive to new physics, because the contribution to this decay in the Standard Model (SM) is highly suppressed and known very accurately; the branching ratio is $3\times 10^{-11}$ in the SM with a theoretical uncertainty …

R&D on a high-performance electromagnetic calorimeter based on oriented crystalline scintillators

M. Soldani, N. Argiolas, L. Bandiera, V.G. Baryshevsky et autres

Although inorganic scintillators are widely used in the design of electromagnetic calorimeters for high-energy physics and astrophysics, their crystalline nature and, hence, their lattice orientation are generally neglected in the detector design. However, in general, the features of the electromagnetic field experienced …
