“…In global fits, the strange PDF is mostly constrained by the neutrino-induced deep-inelastic scattering data, such as CHORUS, NuTeV and NO-MAD [36,37,169,170]. While also inclusive data is sensitive to strangeness, the strongest constraint come from the so-called dimuon process, charm production in charged-current DIS.…”

We present NNPDF3.0, the first set of parton distribution functions (PDFs) determined with a methodology validated by a closure test. NNPDF3.0 uses a global dataset including HERA-II deep-inelastic inclusive cross-sections, the combined HERA charm data, jet production from ATLAS and CMS, vector boson rapidity and transverse momentum distributions from ATLAS, CMS and LHCb, W +c data from CMS and top quark pair production total cross sections from ATLAS and CMS. Results are based on LO, NLO and NNLO QCD theory and also include electroweak corrections. To validate our methodology, we show that PDFs determined from pseudo-data generated from a known underlying law correctly reproduce the statistical distributions expected on the basis of JHEP04(2015)040the assumed experimental uncertainties. This closure test ensures that our methodological uncertainties are negligible in comparison to the generic theoretical and experimental uncertainties of PDF determination. This enables us to determine with confidence PDFs at different perturbative orders and using a variety of experimental datasets ranging from HERA-only up to a global set including the latest LHC results, all using precisely the same validated methodology. We explore some of the phenomenological implications of our results for the upcoming 13 TeV Run of the LHC, in particular for Higgs production cross-sections.

“…The results can also be used to correct for acceptance in experimental analyses. In this Letter, we show comparisons of our results with data from the NuTeV and NOMAD collaborations [10,11], indicating that, once the NNLO corrections are included, slightly higher strangeness PDFs are preferred in the low-x region than those based on a NLO analysis.…”

“…Approximate NNLO [15] results are available for a very large momentum transfer. However, for neutrino DIS experiments [10,11,16,17], the typical momentum transfer is small and the exact charm-quark mass dependence must be kept [15,18]. Recently, Oðα 3 s Þ results [19] became available for structure function xF 3 at large momentum transfer.…”

We present a fully differential next-to-next-to-leading order calculation of charm-quark production in charged-current deep-inelastic scattering, with full charm-quark mass dependence. The next-to-next-toleading order corrections in perturbative quantum chromodynamics are found to be comparable in size to the next-to-leading order corrections in certain kinematic regions. We compare our predictions with data on dimuon production in (anti)neutrino scattering from a heavy nucleus. Our results can be used to improve the extraction of the parton distribution function of a strange quark in the nucleon. DOI: 10.1103/PhysRevLett.116.212002 Introduction.-Charm-quark (c) production in deepinelastic scattering (DIS) of a neutrino from a heavy nucleus provides direct access to the strange-quark (s) content of the nucleon. At lowest order, the relevant partonic process is neutrino interaction with a strange quark, νs → cl, mediated by weak vector boson W exchange. Another source of constraints is charm-quark production in association with a W boson at hadron colliders, gs → cW. The DIS data determine parton distribution functions (PDFs) in the nucleon whose detailed understanding is vital for precise predictions at the Large Hadron Collider (LHC). The strangequark PDF can play an important role in LHC phenomenology, contributing, for example, to the total PDF uncertainty in W or Z boson production [1,2], and to systematic uncertainties in precise measurements of the W boson mass and weak-mixing angle [3][4][5]. It is estimated that the PDF uncertainty of the strange quark alone could lead to an uncertainty of about 10 MeV on the W boson mass measurement at the LHC [6]. From the theoretical point of view, it is important to test whether the strange PDFs are suppressed compared to those of other light sea quarks, related to the larger mass of the strange quark, as suggested by various models [7][8][9], and to establish whether there is a difference between the strange-and antistrange-quark PDFs.In this Letter, we report on a complete calculation at next-to-next-to-leading order (NNLO) in pertubative quantum chromodynamics (QCD) of charm-quark production in DIS of a neutrino from a nucleon. Our calculation is based on a phase-space slicing method and uses a fully differential Monte Carlo integration. It maintains the exact mass dependence and all kinematic information at the parton level. The NNLO corrections can change the cross sections by up to 10%, depending on the kinematic region considered. Our results show that the next-to-leading-order (NLO) predictions underestimate the perturbative uncertainties
