Scalaron-driven Dark Matter during Warm Inflation via UV Freeze--in

F. Millo

We investigate the production of Dark Matter (DM) within the warm Higgs--Starobinsky (HS) inflation. By adopting the ultraviolet (UV) freeze--in mechanism -- where the DM number de…

Photons, jets and missing momentum from a two-vector dark sector

Yara do Amaral Coutinho, Benjamin Fuks, Mark D. Goodsell +5

We investigate the LHC phenomenology of a vector dark-sector effective theory containing two neutral massive vector states, both odd under a dark-parity symmetry. The lightest stat…

Photoinduced enhancement of chemical shift sensitivity to local vibrations

Ana Martínez Gutiérrez, Oliver Alexander, Pablo Estévez Alonso +26

The advent of novel free-electron laser sources enabling time-resolved x-ray photoelectron spectroscopy (tr-XPS) provides a unique opportunity to monitor local chemical environment…

Deciphering compressed electroweakino excesses with MadAnalysis 5

Jack Y. Araz, Benjamin Fuks, Mark D. Goodsell +1

We present version 1.11 of MadAnalysis 5, which extends the software package in several major ways to improve the handling of efficiency tables, the computation of observables in d…
