Pinpointing the Mechanism of Neutrinoless Weak Decays with Positrons
Julia Harz, George A. Parker
Neutrinoless double beta decay is the flagship laboratory probe of a Majorana contribution to the neutrino mass. However, besides the standard mass mechanism other higher- dimensio…
Impact of dim-6 SMEFT operators on low-scale leptogenesis
Kaori Fuyuto, Julia Harz, Sascha Weber
The paper studies how a dimension‑six lepton‑number‑conserving operator in the neutrino‑extended SMEFT modifies the production and equilibration of right‑handed neutrinos in low‑sc…
Sommerfeld Effect and Bound State Formation for Dark Matter Models with Colored Mediators with SE+BSF4DM
Mathias Becker, Emanuele Copello, Julia Harz +1
In the universal framework of simplified -channel dark matter models, the calculation of the relic abundance can be dominated by mediator annihilation when the dark matter and m…
Manual for SE+BSF4DM -- A micrOMEGAs package for Sommerfeld Effect and Bound State Formation in colored Dark Sectors
Mathias Becker, Emanuele Copello, Julia Harz +1
This manual describes the usage and implementation of SE+BSF4DM, an add-on package for micrOMEGAs that includes the Sommerfeld effect and bound state formation in the numerical eva…
Radiative neutrino masses from dim-7 SMEFT: a simplified multi-scale approach
Kåre Fridell, Lukáš Gráf, Julia Harz +1
Lepton-number-violating interactions occur in the Standard Model Effective Field Theory (SMEFT) at odd dimensions starting from the dimension-5 Weinberg operator. Although the oper…
t-channel dark matter at the LHC -- a whitepaper
Chiara Arina, Benjamin Fuks, Luca Panizzi +67
This report, summarising work achieved in the context of the LHC Dark Matter Working Group, investigates the phenomenology of -channel dark matter models, spanning minimal setup…
