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

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

Evaluation of the Theoretical Uncertainties in the Z to ll Cross Sections at the LHC
, 2008 We study the sources of systematic errors in the measurement of the Z to ll cross-sections at the LHC. We consider the systematic errors in both the total cross-section and acceptance for anticipated experimental cuts.

Strongly Interacting Dynamics beyond the Standard Model on a Spacetime Lattice
, 2010 Strong theoretical arguments suggest that the Higgs sector of the Standard Model of the Electroweak interactions is an effective low-energy theory, with a more fundamental theory that is expected to emerge at an energy scale of the order of the TeV.

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 ...

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 ...

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 ...

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 ...
