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.

Precision measurement of the mass and width of the W boson at CDF [PDF]
, 2010 A precision measurement of the mass and width of the W boson is presented. The W bosons are produced in proton antiproton collisions occurring at a centre of mass energy of 1.96 TeV at the Tevatron accelerator.

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.

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

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.

Towards the two-loop electroweak corrections to the Drell-Yan process: the infrared structure
Journal of High Energy PhysicsWe discuss the lepton-pair production process in Quantum Electrodynamics. We present the ultraviolet-renormalised and infrared-subtracted finite contribution of the second-order virtual corrections to the inclusive lepton-pair production cross section u ...

Learning Feynman integrals from differential equations with neural networks
Journal of High Energy PhysicsWe perform an exploratory study of a new approach for evaluating Feynman integrals numerically. We apply the recently-proposed framework of physics-informed deep learning to train neural networks to approximate the solution to the differential equations ...
