The partonic structure of the electron at the next-to-leading logarithmic accuracy in QED
By working in QED, we obtain the electron, positron, and photon Parton Distribution Functions (PDFs) of the unpolarised electron at the next-to-leading logarithmic accuracy.

Charge asymmetry in electron/positron energy loss in nuclear Bremsstrahlung
We calculate the leading Coulomb correction to the Bremsstrahlung energy loss in the electron-nucleus collisions for arbitrary energy of the incoming particle. This correction determines the charge asymmetry, i.e., the difference of electron and positron

We present the analytic calculation of the Master Integrals necessary to compute the planar massive QCD corrections to Di-photon (and Di-jet) production at hadron colliders. The master integrals are evaluated by means of the differential equations method

Muon-electron scattering at NLO
We consider the process of muon-electron elastic scattering, which has been proposed as an ideal framework to measure the running of the electromagnetic coupling constant at space-like momenta and determine the leading-order hadronic contribution to the ...

Mixed QCD-EW corrections for Higgs leptonic decay via HW + W − vertex
We consider the two-loop corrections to the HW + W − vertex at order αα s . We construct a canonical basis for the two-loop integrals using the Baikov representation and the intersection theory.

We complete the analytic evaluation of the master integrals for the two-loop non-planar box diagrams contributing to the top-pair production in the quark-initiated channel, at next-to-next-to-leading order in QCD.

Two-loop perturbative corrections to the constrained effective potential in thermal QCD
In this paper, we compute the constrained QCD effective potential up to two-loop order with finite quark mass and chemical potential. We present the explicit calculations by using the double line notation and analytical expressions for massless quarks ...

Diphoton production in vector-boson scattering at the LHC at next-to-leading order QCD
In this paper, we present results at next-to-leading order (NLO) QCD for photon pair production in association with two jets via vector boson scattering within the Standard Model (SM), and also in an effective field theory framework with anomalous gauge ...

Master integrals for the NNLO virtual corrections to μe scattering in QED: the planar graphs
We evaluate the master integrals for the two-loop, planar box-diagrams contributing to the elastic scattering of muons and electrons at next-to-next-to leading-order in QED.

QCD static force in gradient flow
We compute the QCD static force and potential using gradient flow at next-to-leading order in the strong coupling. The static force is the spatial derivative of the static potential: it encodes the QCD interaction at both short and long distances.
