PHOTON-2017 conference proceedings
David d'Enterria, Albert de Roeck, Michelangelo Mangano +77
This document collects the proceedings of the PHOTON 2017 conference ("International Conference on the Structure and the Interactions of the Photon", including the 22th "Internatio…
Renormalization of mixing angles
Ansgar Denner, Stefan Dittmaier, Jean-Nicolas Lang
We discuss the renormalization of mixing angles for theories with extended scalar sectors. Motivated by shortcomings of existing schemes for mixing angles, we review existing renor…
Electroweak corrections in the Two-Higgs-Doublet Model and a Singlet Extension of the Standard Model
Lukas Altenkamp, Michele Boggia, Stefan Dittmaier +1
We present the next-to-leading-order calculation of the partial decay widths of light CP-even Higgs bosons decaying into four fermions in the Two-Higgs-Doublet Model and a Singlet…
Precise predictions for same-sign W-boson scattering at the LHC
Alessandro Ballestrero, Benedikt Biedermann, Simon Brass +21
Vector-boson scattering processes are of great importance for the current run-II and future runs of the Large Hadron Collider. The presence of triple and quartic gauge couplings in…
Higgs-boson decay to four fermions in the Two-Higgs-Doublet Model and Prophecy4f
Lukas Altenkamp, Stefan Dittmaier, Heidi Rzehak
We present the next-to-leading-order calculation of the partial decay widths of the light CP-even Higgs boson decaying into four fermions in the Two-Higgs-Doublet Model. The four d…
Precision calculations for fermions in a Singlet Extension of the Standard Model with Prophecy4f
Lukas Altenkamp, Michele Boggia, Stefan Dittmaier
We consider an extension of the Standard Model by a real singlet scalar field with a -symmetric Lagrangian and spontaneous symmetry breaking with vacuum expectation value for…
