Top Quark Flavor Changing Couplings at a Muon Collider
Advances in High Energy Physics, Volume 2024, Issue 1, 2024.There is growing interest in the development of a muon collider that would make it possible to produce lepton collisions at energies of several TeV. Among others, there can be significant contributions to electroweak gauge boson, Higgs boson, and top quark physics.

Advances in High Energy Physics, Volume 2024, Issue 1, 2024.The measurements of the total cross section of the e+e−⟶γγ(γ) reaction from the VENUS, TOPAS, OPAL, DELPHI, ALEPH, and L3 collaborations, collected between 1989 and 2003, are used to perform a χ2 test to validate the current quantum electrodynamics (QED) theory and search for possible deviations with the direct contact term annihilation. By observing a

Massive two-loop four-point Feynman integrals at high energies with AsyInt
Journal of High Energy PhysicsWe present analytic techniques for parametric integrations of massive two-loop four-point Feynman integrals at high energies, and their implementation in the toolbox AsyInt. In the high-energy region, the Feynman integrals involving external and internal

Two-loop mass splittings in electroweak multiplets: winos and minimal dark matter
, 2018 The radiatively-induced splitting of masses in electroweak multiplets is relevant for both collider phenomenology and dark matter. Precision two-loop corrections of $\mathcal{O}$(MeV) to the triplet mass splitting in the wino limit of the minimal ...

Testing the neutrino content of the muon at muon colliders
Journal of High Energy PhysicsCollinear emission of W bosons off a high-energy muon induces a large muon-neutrino component among the Parton Distribution Functions (PDFs) of a muon. In this paper we study the phenomenology related to the ν μ PDF at future high-energy muon colliders ...

Corrections of Order $\alpha \alpha_s$ to W Boson Decays
, 2013 We present the calculation of the mixed two-loop QCD/electroweak corrections to hadronic W boson decays within the Standard Model. The optical theorem is applied to the W boson two-point function.

Electroweak corrections to Higgs+jet production in gluon fusion
Journal of High Energy PhysicsWe present the calculation of complete next-to-leading order electroweak corrections to the Higgs boson production in gg → gH channel. We apply the method of differential equations combined with the selection of optimized master integrals to accomplish ...

Two-loop running effects in Higgs physics in Standard Model Effective Field Theory
Journal of High Energy PhysicsWe consider the renormalization group equations within the Standard Model Effective Field Theory and compute two-loop contributions proportional to the top quark Yukawa coupling for the operator generating an effective Higgs-gluon coupling, focusing on ...
