TREE-LEVEL PROCESSES This chapter describes in some detail the tree-level computations of some elementary standard model processes. Both leptons and quarks are treated on the …

The word Muonde refers to indigenous fig trees of this semi-arid region, especially the big beautiful free-standing Ficus sur. This is a tree associated with fruits and birds and life. It is …

2021年6月21日 · However, within the advent of the Standard Model (SM) of particle physics in the late 1960s, it was recognized that the electron, muon and tau leptons have after all very similar …

Proposed Minimal Supersymmetric Standard Model one-loop corrections to the muon g−2 involving particles beyond the standard model: a neutralino and a smuon, and a chargino and …

In this work, we present a realistic proposal and a comprehensive study of quantum entanglement in a state composed of diferent-flavor fermions in muon-electron scattering. The polarization …

μ子（Muon），又称渺子、缪子，是一种轻子，它带有-1的基本电荷及1/2的自旋。 缪子是自然界的基本粒子之一，具有极强的穿透能力，可以实现大型目标物的无接触、深穿透和无损成像， …

Inverse muon decay ( e− → e −) is a promising tool to constrain neutrino uxes with energies E ≥10:9 GeV. Radiative corrections introduce percent-level distortions to energy spectra of …

Consider 2 processes in QED: (a) elastic electron-muon scattering e−μ− → e−μ−, and (b) muon pair production e−e+ → μ−μ+. At the tree level there is one Feynman diagram for each …

2019年11月1日 · In this paper I review the present status of the search for muon decays beyond the Standard Model, with a special attention to the most conventional muon lepton flavor …

2022年4月1日 · The Mu3e experiment at the Paul Scherrer Institut will search for the lepton-number-violating decay \mueee, extending the sensitivity by four orders of magnitude …
