NLO computation of diffractive di-hadron production in a saturation framework

open access: yesJournal of High Energy Physics, 2023
Abstract The cross-sections of diffractive double hadron photo- or electroproduction with large pT, on a nucleon or a nucleus, are calculated to NLO accuracy. A hybrid formalism mixing collinear factorization and high energy small-x factorization, more precisely the shockwave formalism for the latter, is used to derive the results.

Precise yield of high-energy photons from Higgsino dark matter annihilation

open access: yesJournal of High Energy Physics, 2020
The impact of electroweak Sudakov logarithms on the endpoint of the photon spectrum for wino dark matter annihilation was studied intensively over the last several years. In this work, we extend these results to Higgsino dark matter χ 1 0 $$ {\chi}_1^0 $$

Virtual corrections to gg → ZH via a transverse momentum expansion

open access: yesJournal of High Energy Physics, 2021
We compute the next-to-leading virtual QCD corrections to the partonic cross section of the production of a Higgs boson in association with a Z boson in gluon fusion.

Electroweak corrections to diphoton plus jets

open access: yesJournal of High Energy Physics, 2017
We calculate the next-to-leading order electroweak corrections to the production of a photon pair in association with zero, one and two jets at the LHC. We use GoSam and Sherpa to obtain the results in a fully automated way. For a typical set of fiducial

Measurement of the electron charge asymmetry in inclusive W production in pp collisions at √s = 7 TeV in the CMS experiment. [PDF]

open access: yes, 2013
In this thesis, two measurements of the electron charge asymmetry in inclusive W boson production with the CMS detector are presented. The measurements are obtained from proton-proton collision data with sqrt(s) = 7 TeV.

Meromorphic solutions of recurrence relations and DRA method for multicomponent master integrals

open access: yesJournal of High Energy Physics, 2018
We formulate a method to find the meromorphic solutions of higher-order recurrence relations in the form of the sum over poles with coefficients defined recursively. Several explicit examples of the application of this technique are given.

Mixed QCD-EW corrections for Higgs leptonic decay via HW + W − vertex

open access: yesJournal of High Energy Physics, 2021
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.

Constructing All-Order Corrections to Multi-Jet Rates [PDF]

open access: yes, 2009
We discuss the universal behaviour of scattering cross sections in the limit of infinite rapidity separation between all produced particles, and illustrate the behaviour explicitly for the production of n jets, W+n jets, Z+n jets for n=2,3,4, and for H+2,

Non-planar elliptic vertex

open access: yesJournal of High Energy Physics, 2022
We consider the problem of obtaining higher order in regularization parameter ε analytical results for master integrals with elliptics. The two commonly employed methods are provided by the use of differential equations and direct integration of ...

Measurement of the low-mass Drell-Yan differential cross section at √s = 7 TeV using the ATLAS detector [PDF]

open access: yes, 2014
The differential cross section for the process Z/γ ∗ → ℓℓ (ℓ = e, μ) as a function of dilepton invariant mass is measured in pp collisions at s√ = 7 TeV at the LHC using the ATLAS detector.
