Associated production of a boson and massive bottom quarks at next-to-next-to-leading order in QCD
Luca Buonocore, Simone Devoto, Stefan Kallweit +3
We present the first calculation for the hadroproduction of a boson in association with a massive bottom () quark-antiquark pair at next-to-next-to-leading order (NNLO) in Q…
Renormalizable Extension of the Abelian Higgs-Kibble Model with a Dim.6 Derivative Operator
Daniele Binosi, Andrea Quadri
We present a new approach to the consistent subtraction of a non power-counting renormalizable extension of the Abelian Higgs-Kibble (HK) model supplemented by a dim.6 derivative-d…
Theory pipeline for PDF fitting
Andrea Barontini, Alessandro Candido, Juan Cruz-Martinez +3
Fitting PDFs requires the integration of a broad range of datasets, both from data and theory side, into a unique framework. While for data the integration mainly consists in the s…
Improved Factorization for Threshold Resummation in Heavy Quark to Heavy Quark Decays
U. G. Aglietti, G. Ferrera
We consider the resummation of soft-gluon effects in heavy quark to heavy quark decays, namely the processes Q1 -> Q2 + (non QCD partons), where Q1 and Q2 are two different heavy q…
Projected transverse momentum resummation in top-antitop pair production at LHC
Wan-Li Ju, Marek Schönherr
The transverse momentum distribution of the system is of both experimental and theoretical interest. In the presence of the azimuthally asymmetric divergences, pursuing…
Higgs boson production in association with a top-antitop quark pair in next-to-next-to leading order QCD
Stefano Catani, Simone Devoto, Massimiliano Grazzini +3
The associated production of a Higgs boson with a top-antitop quark pair is a crucial process at the LHC since it allows for a direct measurement of the top-quark Yukawa coupling.…
Local analytic sector subtraction for initial- and final-state radiation at NLO in massless QCD
Gloria Bertolotti, Paolo Torrielli, Sandro Uccirati +1
Within the framework of local analytic sector subtraction, we present the subtraction of next-to-leading-order QCD singularities for processes featuring massless coloured particles…
Parton Distributions and New Physics Searches: the Drell-Yan Forward-Backward Asymmetry as a Case Study
Richard D. Ball, Alessandro Candido, Stefano Forte +4
We discuss the sensitivity of theoretical predictions of observables used in searches for new physics to parton distributions (PDFs) at large momentum fraction . Specifically, w…
Evidence for intrinsic charm quarks in the proton
Richard D. Ball, Alessandro Candido, Juan Cruz-Martinez +6
The theory of the strong force, quantum chromodynamics, describes the proton in terms of quarks and gluons. The proton is a state of two up quarks and one down quark bound by gluon…
Resummation effects in the bottom-quark fragmentation function
Fabio Maltoni, Giovanni Ridolfi, Maria Ubiali +1
We compute the perturbative component of the fragmentation function of the quark to the best of the present theoretical knowledge. The fixed-order calculation to order …
Anomalous Higgs boson couplings in weak boson fusion production at NNLO in QCD
Konstantin Asteriadis, Fabrizio Caola, Kirill Melnikov +1
The production of Higgs bosons in weak boson fusion has the second largest cross section among Higgs-production processes at the LHC. As such, this process plays an important role…
Sensitivity to New Physics in final states with multiple gauge and Higgs bosons
Alessandra Cappati, Roberto Covarelli, Paolo Torrielli +1
We analyse the sensitivity to beyond-the-Standard-Model effects of hadron-collider processes involving the interaction of two electroweak and two Higgs bosons, VVHH, with V being e…
Evaluation of Feynman integrals with arbitrary complex masses via series expansions
Tommaso Armadillo, Roberto Bonciani, Simone Devoto +2
We present an algorithm to evaluate multiloop Feynman integrals with an arbitrary number of internal massive lines, with the masses being in general complex-valued, and its impleme…
False vacuum decay: an introductory review
Federica Devoto, Simone Devoto, Luca Di Luzio +1
We review the description of tunnelling phenomena in the semi-classical approximation in ordinary quantum mechanics and in quantum field theory. In particular, we describe in detai…
The PDF4LHC21 combination of global PDF fits for the LHC Run III
Richard D. Ball, Jon Butterworth, Amanda M. Cooper-Sarkar +19
A precise knowledge of the quark and gluon structure of the proton, encoded by the parton distribution functions (PDFs), is of paramount importance for the interpretation of high-e…
Mixed QCD-electroweak corrections to dilepton production at the LHC in the high invariant mass region
Federico Buccioni, Fabrizio Caola, Herschel A. Chawdhry +6
We compute mixed QCD-electroweak corrections to the neutral-current Drell-Yan production of a pair of massless leptons in the high invariant mass region. Our computation is fully d…
Snowmass 2021 whitepaper: Proton structure at the precision frontier
S. Amoroso, A. Apyan, N. Armesto +54
An overwhelming number of theoretical predictions for hadron colliders require parton distribution functions (PDFs), which are an important ingredient of theory infrastructure for…
Determination of the strong-coupling constant from the -boson transverse-momentum distribution
Stefano Camarda, Giancarlo Ferrera, Matthias Schott
The strong-coupling constant is determined from the low-momentum region of the transverse-momentum distribution of bosons produced through the Drell-Yan process, using predicti…
Higgs boson production at the LHC: fast and precise predictions in QCD at higher orders
Stefano Camarda, Leandro Cieri, Giancarlo Ferrera +1
We present a new numerical program, HTurbo, which provides fast and numerically precise predictions for Higgs boson production cross sections. The present version of the code imple…
Two sides of the same coin: sterile neutrinos and dark radiation. Status and perspectives
Maria Archidiacono, Stefano Gariazzo
The presence of light sterile neutrinos is one of the unanswered questions of particle physics. The cosmological counterpart is represented by dark radiation, i.e.\ any form of rad…

Alessandro Candido, Felix Hekhorn, Giacomo Magni
We present a new QCD evolution library for unpolarized parton distribution functions: EKO. The program solves DGLAP equations up to next-to-next-to-leading order. The unique featur…
