Probing dark sector fermions in Higgs precision studies and direct searches
Ayres Freitas, Qian Song
In this paper, we investigate the discovery prospect of simplified fermionic dark sectors models through Higgs precision measurements at colliders and direct searches at h…
Fermionic Electroweak NNLO Corrections to with Polarized Beams and Different Renormalization Schemes
Ayres Freitas, Qian Song, Keping Xie
Recently, the next-to-next-to-leading order (NNLO) electroweak corrections with fermion loops to the Higgsstrahling process were computed. Here we present numerical results for pol…
GRIFFIN: A C++ library for electroweak radiative corrections in fermion scattering and decay processes
Lisong Chen, Ayres Freitas
This paper describes a modular framework for the description of electroweak scattering and decay processes, including but not limited to Z-resonance physics. The framework consiste…
Report of the Topical Group on Electroweak Precision Physics and Constraining New Physics for Snowmass 2021
Alberto Belloni, Ayres Freitas, Junping Tian +65
The precise measurement of physics observables and the test of their consistency within the standard model (SM) are an invaluable approach, complemented by direct searches for new…
Two-Loop Electroweak Corrections with Fermion Loops to
Ayres Freitas, Qian Song
We present a complete calculation of the next-to-next-to-leading (NNLO) electroweak corrections involving closed fermion loops to the process. This has been achiev…
Hadronic effects in Møller scattering at NNLO
Jens Erler, Rodolfo Ferro-Hernández, Ayres Freitas
Two-loop electroweak corrections to polarized Moller scattering are studied in two different schemes at low energies. We find the finite corrections to be well under control.…
