Selection rules for charged lepton flavour violating processes from residual flavour groups
Lorenzo Calibbi, Claudia Hagedorn, Michael A. Schmidt +1
We systematically investigate the possible phenomenological impact of residual flavour groups in the charged lepton sector. We consider all possible flavour charge assignments for…
Low-scale seesaw with flavour and CP symmetries $\unicode{x2013}$ from colliders to leptogenesis
Marco Drewes, Yannis Georis, Claudia Hagedorn +1
We consider an extension of the Standard Model with three right-handed neutrinos, endowed with a flavour symmetry , or , , and CP.…
Charged lepton flavour violation from inverse seesaw with flavour and CP symmetries
F. P. Di Meglio, C. Hagedorn
We study charged lepton flavour violation in a scenario in which light neutrino masses are generated via the inverse seesaw mechanism with 3+3 gauge singlet fermions, Ni and Sj, i,…
Flavon vacuum alignment beyond SUSY
Claudia Hagedorn, M. L. López-Ibáñez, M. Jay Pérez +2
In flavor models the vacuum alignment of flavons is typically achieved via the -terms of certain fields in the supersymmetric limit. We propose a method for preserving such alig…
Low-scale leptogenesis with flavour and CP symmetries
Marco Drewes, Yannis Georis, Claudia Hagedorn +1
We consider a type-I seesaw framework with a flavour symmetry from the series of non-abelian groups and and a CP symmetry. Breaking these symmetries non-trivi…
Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
Lepton Mixing from Delta (3 n^2) and Delta (6 n^2) and CP
C. Hagedorn, A. Meroni, E. Molinaro
We perform a detailed study of lepton mixing patterns arising from a scenario with three Majorana neutrinos in which a discrete flavor group Gf=Delta (3 n^2) or Gf=Delta(6 n^2) and…
SUSY S4 x SU(5) revisited
Claudia Hagedorn, Stephen F. King, Christoph Luhn
Following the recent results from Daya Bay and RENO, which measure the lepton mixing angle theta^l_13 ~ 0.15, we revisit a supersymmetric S4 x SU(5) model, which predicts tri-bimax…
Charged Lepton Flavour Violating Radiative Decays in See-Saw Models with Symmetry
C. Hagedorn, E. Molinaro, S. T. Petcov
The charged lepton flavour violating (LFV) radiative decays, , and are investigated in a class of supersymmetric models with three heavy righ…
Minimal Mass Matrices for Dirac Neutrinos
C. Hagedorn, W. Rodejohann
We consider the possibility of neutrinos being Dirac particles and study minimal mass matrices with as much zero entries as possible. We find that up to 5 zero entries are allowed.…
