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

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

NLO ACTIVITY AND COMPUTATIONAL DISCUSSION OF HALOGEN-SUBSTITUTED CHALCONE DERIVATIVES
RASAYAN Journal of Chemistry, 2023 The four halogen-substituted chalcones 1–4 have been synthesized and analyzed to FT-Infrared, UV-Visible, GC-MS spectrometer, and 1D NMR (1H and 13C) spectroscopy techniques. Computational calculations were carried out for geometrical optimization of structure regards bond length, bond angle, and torsional angle estimated.

Extending the MINLO method [PDF]
, 2016 We consider improving POWHEG+MINLO simulations, so as to also render them NLO accurate in the description of observables receiving contributions from events with lower parton multiplicity than present in their underlying NLO calculation.

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

t tbar W and t tbar Z Hadroproduction at NLO accuracy in QCD with Parton Shower and Hadronization effects [PDF]
, 2012 We present theoretical predictions for the hadroproduction of t tbar W+, t tbar W- and t tbar Z at LHC as obtained by matching numerical computations at NLO accuracy in QCD with Shower Monte Carlo programs. The calculation is performed by PowHel, relying
