phenomenological point of view. A plethora of neutrino mass models, known collectively as …

A call for new physics: the muon anomalous magnetic moment and lepton flavor violation

M Lindner, M Platscher, FS Queiroz - Physics Reports, 2018 - Elsevier
We review how the muon anomalous magnetic moment (g− 2) and the quest for lepton flavor
violation are intimately correlated. Indeed the decay μ→ e γ is induced by the same …

Toward deconstructing the simplest seesaw mechanism

S Mandal, OG Miranda, GS Garcia, JWF Valle, XJ Xu - Physical Review D, 2022 - APS
The triplet or type-II seesaw mechanism is the simplest way to endow neutrinos with mass in
the Standard Model (SM). Here we review its associated theory and phenomenology …
