TL;DR: In this article, the authors search for rare FCNC charm decays of the form $X_c+\to h^+\llp, where X_c^+$ is a charm hadron, $h$ are a pion, kaon or proton, and $\ell^{(}{'}^{)}$ is an electron or a muon.

TL;DR: In this article , the optimal control problem with quadratic functionals for a linear Volterra integro-differential equation in Hilbert spaces was studied, and a closed-loop form of the unique optimal control via certain operators that are shown to solve a coupled system of quad-ratic differential equations was obtained.

TL;DR: The ring imaging Cherenkov detector of the NA62 experiment at the CERN SPS is a key element of particle identification in the NA 62 experimental strategy as mentioned in this paper, which fulfills different conditions: to distinguish pions from muons with a muon rejection factor of O(10 2 ) in the NE momentum range of operation, between 15 and 35 GeV/c.

TL;DR: The NA62 experiment at CERN Super Proton Synchrotron was designed to measure BR(K+ → π+νv¯) with an in-fight technique, never used before for this measurement.

TL;DR: The NA62 experiment at CERN reports searches for K + → e + N , K + + → µ + N and K+ → µ+ X decays, where N and X are massive invisible particles, using the 2016-2018 data set as mentioned in this paper .
