The MUonE experiment aims at providing a novel determination of the leading hadronic contribution to muon anomalous magnetic moment through study elastic muon-electron scattering. Since initial-state electrons are bound in low-Z atomic target, interaction between incoming muons and nuclei is expected be main source experimental background. In this article, we production real lepton pair from muon-nucleus scattering, discussing its numerical impact kinematic configuration. process described...
The electric dipole moments~(EDM) of fundamental particles inherently violate parity~(P) and time-reversal~(T) symmetries. By virtue the CPT theorem in quantum field theory, latter also implies violation combined charge-conjugation parity~(CP) symmetry. We aim to measure EDM muon using frozen-spin technique within a compact storage trap. This method exploits high effective field, \$E \approx 165\$ MV/m, experienced rest frame with momentum about 23 MeV/c when it passes through solenoidal...
We present an improved theoretical prediction of the positron energy spectrum for polarised Michel decay $\mu^+\to e^+ \nu_e\bar{\nu}_\mu$. In addition to full next-to-next-to-leading order correction $\alpha^2$ in electromagnetic coupling, we include logarithmically enhanced terms at even higher orders. Logarithms due collinear emission are included next-to-leading accuracy up $\alpha^4$. At endpoint spectrum, soft photon results large logarithms that resummed logarithmic accuracy. apply...

The state-of-the-art research at the intensity frontier of particle physics aims to find evidence for new beyond Standard Model by searching faint signals in a vast amount background. To this end, detectors with excellent resolution all kinematic variables are required. For future calorimeters, very promising material is LYSO, due its short radiation length, fast decay time and good light yield. In article, simulation calorimeter assembled from multiple large LYSO crystals presented....

This work presents an improved simulation decay II, based on McMule Geant4.
