A Monte Carlo global analysis of the Standard Model Effective Field Theory: the top quark sector
Nathan P. Hartland, Fabio Maltoni, Emanuele R. Nocera +4
We present a novel framework for carrying out global analyses of the Standard Model Effective Field Theory (SMEFT) at dimension-six: SMEFiT. This approach is based on the Monte Car…
Charged hadron fragmentation functions from collider data
The NNPDF Collaboration, Valerio Bertone, Nathan P. Hartland +3
We present NNFF1.1h, a new determination of unidentified charged-hadron fragmentation functions (FFs) and their uncertainties. Experimental measurements of transverse-momentum dist…
Illuminating the photon content of the proton within a global PDF analysis
Valerio Bertone, Stefano Carrazza, Nathan P. Hartland +1
Precision phenomenology at the LHC requires accounting for both higher-order QCD and electroweak corrections as well as for photon-initiated subprocesses. Building upon the recent…
Minimisation strategies for the determination of parton density functions
Stefano Carrazza, Nathan P. Hartland
We discuss the current minimisation strategies adopted by research projects involving the determination of parton distribution functions (PDFs) and fragmentation functions (FFs) th…
A determination of the fragmentation functions of pions, kaons, and protons with faithful uncertainties
Valerio Bertone, Stefano Carrazza, Nathan P. Hartland +2
We present NNFF1.0, a new determination of the fragmentation functions (FFs) of charged pions, charged kaons, and protons/antiprotons from an analysis of single-inclusive hadron pr…
Parton distributions from high-precision collider data
The NNPDF Collaboration, Richard D. Ball, Valerio Bertone +13
We present a new set of parton distributions, NNPDF3.1, which updates NNPDF3.0, the first global set of PDFs determined using a methodology validated by a closure test. The update…
Parton Radiation and Fragmentation from LHC to FCC-ee
David d'Enterria, Peter Z. Skands, D. Anderle +53
This document collects the proceedings of the "Parton Radiation and Fragmentation from LHC to FCC-ee" workshop (http://indico.cern.ch/e/ee\_jets16) held at CERN in Nov. 2016. The w…
Pinning down the large-x gluon with NNLO top-quark pair differential distributions
Michał Czakon, Nathan P. Hartland, Alexander Mitov +2
Top-quark pair production at the LHC is directly sensitive to the gluon PDF at large x. While total cross-section data is already included in several PDF determinations, differenti…
Double Higgs production from at a 100 TeV hadron collider
Nathan P. Hartland
In this contribution we study the prospects of measuring double Higgs production at a potential 100 TeV future circular collider. We apply an analysis procedure that utilises recon…
Physics at a 100 TeV pp collider: Higgs and EW symmetry breaking studies
R. Contino, D. Curtin, A. Katz +72
This report summarises the physics opportunities for the study of Higgs bosons and the dynamics of electroweak symmetry breaking at the 100 TeV pp collider.
APFELgrid: a high performance tool for parton density determinations
Valerio Bertone, Stefano Carrazza, Nathan P. Hartland
We present a new software package designed to reduce the computational burden of hadron collider measurements in Parton Distribution Function (PDF) fits. The APFELgrid package conv…
A Determination of the Charm Content of the Proton
The NNPDF Collaboration, Richard D. Ball, Valerio Bertone +7
We present an unbiased determination of the charm content of the proton, in which the charm parton distribution function (PDF) is parametrized on the same footing as the light quar…
Boosting Higgs pair production in the final state with multivariate techniques
J. Katharina Behr, Daniela Bortoletto, James A. Frost +3
The measurement of Higgs pair production will be a cornerstone of the LHC program in the coming years. Double Higgs production provides a crucial window upon the mechanism of elect…
