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…
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…
Impact of dim-6 SMEFT operators on low-scale leptogenesis
Kaori Fuyuto, Julia Harz, Sascha Weber
We investigate the impact of higher-dimensional operators on low-scale leptogenesis (LG) via oscillations of right-handed neutrinos within the neutrino-extended Standard Model Effe…
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…
ALP Production from Abelian Gauge Bosons: Beyond Hard Thermal Loops
Mathias Becker, Julia Harz, Enrico Morgante +2
Previous computations of feebly interacting particle production have encountered issues with unphysical (negative) interaction rates at soft momenta. We address this problem by stu…
