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 ...

Electroweak limits on physics beyond the Standard Mode
EPJ Web of Conferences, 2013 We briefly review the global Standard Model fit to electroweak precision data, and discuss the status of electroweak constraints on new interactions. We follow a general effective Lagrangian approach to obtain modelindependent limits on the dimension-six

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 ...

Electroweak splitting functions in the Standard Model and beyond
Journal of High Energy PhysicsWe derive quasi-collinear factorization formulas in generic spontaneously broken gauge theories with scalars, fermions, and vector bosons. Specifically, we obtain polarized leading-order splitting functions for all possible final-state and initial-state ...

Parity violation in Møller scattering within low-energy effective field theory
Journal of High Energy PhysicsWe include electroweak effects in Møller scattering at low energies in an effective field theory approach and compute the left-right parity-violating asymmetry.

Electron-positron annihilation into heavy leptons at two loops
Journal of High Energy PhysicsWe calculate the NNLO QED corrections to the C-even part of differential cross section of e + e − → μ + μ − process. We neglect power corrections in the electron mass and obtain the result in terms of Goncharov’s polylogarithms.

EVAluation of the Equivalent Vector boson Approximation at highest energy colliders
Journal of High Energy PhysicsCollider processes at the highest available partonic center-of-mass energies — 10 TeV and above — exhibit a new regime of electroweak interactions where electroweak gauge bosons mostly act as quasi-massless partons in vector boson fusion processes.

Fermionic electroweak two-loop corrections to Drell-Yan and related processes
Journal of High Energy PhysicsWe perform a complete calculation of the next-to-next-to-leading order (NNLO) electroweak fermionic corrections to fermion-pair production processes, where “fermionic” refers to contributions with closed fermion loops.

Mixed QCD-EW corrections to W-pair production at electron-positron colliders
Journal of High Energy PhysicsThe discrepancy between the CDF measurement and the Standard Model theoretical prediction for the W-boson mass underscores the importance of conducting high-precision studies on the W boson, which is one of the predominant objectives of proposed future e

Journal of High Energy PhysicsWe consider the transverse momentum (q T ) distribution of neutral charged bosons at hadron colliders. We perform the resummation of the logarithmically-enhanced effects due to simultaneous QCD and QED initial-state radiation, up to mixed next-to-next-to-
