“…About 25 years after next-to-leading order corrections to jet production cross sections in DIS have been studied for the first time [9,10], complete predictions at next-to-nextto-leading order in the strong coupling are now available for inclusive jet and dijet production in DIS [11,12] and in hadron-hadron collisions [13]. These new theoretical developments together with precise measurements and greater kinematic reach of the data allow the use of DIS jet cross sections for precise studies of QCD.…”

A precision measurement of jet cross sections in neutral current deep-inelastic scattering for photon virtualities 5.5 < Q 2 < 80 GeV 2 and inelasticities 0.2 < y < 0.6 is presented, using data taken with the H1 detector at HERA, corresponding to an integrated luminosity of 290 pb −1 . Double-differential inclusive jet, dijet and trijet cross sections are measured simultaneously and are presented as a function of jet transverse momentum observables and as a function of Q 2 . Jet cross sections normalised to the inclusive neutral current DIS cross section in the respective Q 2 -interval are also determined. Previous results of inclusive jet cross sections in the range 150 < Q 2 < 15,000 GeV 2 are extended to low transverse jet momenta 5 < P The data are compared to predictions from perturbative QCD in next-to-leading order in the strong coupling, in approximate next-to-next-to-leading order and in full next-to-nextto-leading order. Using also the recently published H1 jet data at high values of Q 2 , the strong coupling constant α s (M Z ) is determined in next-to-leading order.

“…Over the last few years significant progress has been made in the field of NNLO calculations, allowing for the calculation of processes involving one [9][10][11][12][13][14][15] or two [16,17] massless partons in the final state for the first time. One of the developments that has proven very fruitful for computing NNLO corrections is a novel method for regulating the infrared (IR) singular structure known as N -jettiness slicing (or subtraction).…”

Direct Photon Production at Next-to–Next-to-Leading Order

We present the first calculation of direct photon production at next-to-next-to leading order (NNLO) accuracy in QCD. For this process, although the final state cuts mandate only the presence of a single electroweak boson, the underlying kinematics resembles that of a generic vector boson plus jet topology. In order to regulate the infrared singularities present at this order we use the N -jettiness slicing procedure, applied for the first time to a final state that at Born level includes colored partons but no required jet. We compare our predictions to ATLAS 8 TeV data and find that the inclusion of the NNLO terms in the perturbative expansion, supplemented by electroweak corrections, provides an excellent description of the data with greatly reduced theoretical uncertainties.

“…NNLO corrections to jet production in the the gg-channel have become available recently [82,99]. An approximate NNLO prediction based on threshold resummation (but including all partonic subchannels) was presented in [100].…”

“…Specifically, NNLO corrections are not available for two datasets included in our fit: the vector boson transverse momentum distribution and the W + c rapidity distribution (since there are no NNLO calculations for V +jets and V +heavy quarks). For the jet inclusive cross section, only the gg-channel has been recently computed at NNLO [82,99], while for the full cross section only an approximate NNLO prediction based on threshold resummation is available [100]. For all other observables included in the fit the cross sections are known up to NNLO.…”

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.
