Leading large contributions to Lepton Number Violating Meson Decays
Andrea Donini, Marcela González, Martin Hirsch +1
Lepton number violating meson decays, such as , provide constraints on operators. RGE-improved bounds on the Wilson coefficients of…
Long-Lived HNLs via ALP Portal at the LHC
Rebeca Beltrán, Chandan Hati, Martin Hirsch +1
Heavy neutral leptons (HNLs) and axion-like particles (ALPs) are both considered well-motivated candidates for beyond the standard model (BSM) physics. If ALPs with sizable couplin…
Invisible neutron decay and light BSM particles
J. C. Helo, M. Hirsch, T. Ota
In Standard Model Effective Field Theory (SMEFT), invisible neutron decay arises from d = 12 operators. Adding new light particles to the field content of the SM, such as right-han…
LHC dijet constraints on double beta decay
J. C. Helo, M. Hirsch
We use LHC dijet data to derive constraints on neutrinoless double beta decay. Upper limits on cross sections for the production of "exotic" resonances, such as a right-handed W bo…
Short-range mechanisms of neutrinoless double beta decay at the LHC
J. C. Helo, M. Hirsch, H. Päs +1
Lepton number violation (LNV) mediated by short range operators can manifest itself in both neutrinoless double beta decay and in processes with same sign dilepton final states at…
R-parity Conserving Supersymmetry, Neutrino Mass and Neutrinoless Double Beta Decay
M. Hirsch, H. V. Klapdor-Kleingrothaus, S. G. Kovalenko
We consider contributions of R-parity conserving softly broken supersymmetry (SUSY) to neutrinoless double beta ($\znbb$) decay via the (B-L)-violating sneutrino mass term. The lat…
B-L-violating Masses in Softly Broken Supersymmetry
M. Hirsch, H. V. Klapdor-Kleingrothaus, S. G. Kovalenko
We prove a general low-energy theorem establishing a generic relation between the neutrino Majorana mass and the superpartner sneutrino B-L-violating "Majorana"-like mass term. The…
On the observability of Majoron emitting double beta decays
M. Hirsch, H. V. Klapdor--Kleingrothaus, S. G. Kovalenko +1
Because of the fine--tuning problem in classical Majoron models in recent years several new models were invented. It is pointed out that double beta decays with Majoron emission de…
