PDF4LHC recommendations for LHC Run II

Jon Butterworth, Stefano Carrazza, Amanda Cooper-Sarkar +13

We provide an updated recommendation for the usage of sets of parton distribution functions (PDFs) and the assessment of PDF and PDF+ $α_{s}$ uncertainties suitable for applications a…

High energy resummation of transverse momentum distributions:Higgs in gluon fusion

Stefano Forte, Claudio Muselli

We derive a general resummation formula for transverse-momentum distributions of hard processes at the leading logarithmic level in the high-energy limit, to all orders in the stro…

Resummation ambiguities in the Higgs transverse-momentum spectrum in the Standard Model and beyond

Emanuele Bagnaschi, Robert V. Harlander, Hendrik Mantler +2

We study the prediction for the Higgs transverse momentum distribution in gluon fusion and focus on the problem of matching fixed- and all-order perturbative results. The main sour…

The BMS Equation and c\bar{c} Production; A Comparison of the BMS and BK Equations

Giuseppe Marchesini, A. H. Mueller

We introduce two processes where the BMS equation appears in a context quite different from the original context of non-global jet observables. We note the strong similarities of t…

Evidence of sub-nucleonic degrees of freedom in J/ $ψ$ photoproduction in ultraperipheral collisions at the CERN Large Hadron Collider

E. Andrade-II, I. González, A. Deppman +1

We present calculations for the incoherent photoproduction of J/ $ψ$ vector mesons in ultra-peripheral heavy ion collisions (UPC) in terms of hadronic interactions. This study was c…

Intrinsic charm in a matched general-mass scheme

Richard D. Ball, Valerio Bertone, Marco Bonvini +4

The FONLL general-mass variable-flavour number scheme provides a framework for the matching of a calculation in which a heavy quark is treated as a massless parton to one in which…

Doped Parton Distributions

Valerio Bertone, Stefano Carrazza, Juan Rojo

Calculations of high-energy processes involving the production of b-quarks are typically performed in two different ways, the massive four-flavour scheme (4FS) and the massless fiv…

Parton distributions with threshold resummation

Marco Bonvini, Simone Marzani, Juan Rojo +6

We construct a set of parton distribution functions (PDFs) in which fixed-order NLO and NNLO calculations are supplemented with soft-gluon (threshold) resummation up to NLL and NNL…

On the Impact of Lepton PDFs

Valerio Bertone, Stefano Carrazza, Davide Pagani +1

In this paper we discuss the effect of the complete leading-order QED corrections to the DGLAP equations in the perturbative evolution of parton distribution functions (PDFs). This…

Higgs production in bottom-quark fusion in a matched scheme

Stefano Forte, Davide Napoletano, Maria Ubiali

We compute the total cross-section for Higgs boson production in bottom-quark fusion using the so-called FONLL method for the matching of a scheme in which the $b$ -quark is treated…

The PDF4LHC report on PDFs and LHC data: Results from Run I and preparation for Run II

Juan Rojo, Alberto Accardi, Richard D. Ball +20

The accurate determination of the Parton Distribution Functions (PDFs) of the proton is an essential ingredient of the Large Hadron Collider (LHC) program. PDF uncertainties impact…

Vector boson production at hadron colliders: transverse-momentum resummation and leptonic decay

Stefano Catani, Daniel de Florian, Giancarlo Ferrera +1

We consider the transverse-momentum ( $q_{T}$ ) distribution of Drell-Yan lepton pairs produced, via $W$ and $Z / γ^{*}$ decay, in hadronic collisions. At small values of $q_{T}$ , we resum t…

An Unbiased Hessian Representation for Monte Carlo PDFs

Stefano Carrazza, Stefano Forte, Zahari Kassabov +2

We develop a methodology for the construction of a Hessian representation of Monte Carlo sets of parton distributions, based on the use of a subset of the Monte Carlo PDF replicas…
