TMD densities from the Parton branching method

We present results from a Parton branching solution of the DGLAP equation at LO, NLO and NNLO which is is capable to extract both the collinear part and the transverse momentum de-pendent part of the parton densities. We demonstrate that within our method the collinear part of parton densities exactly corresponds to the semi-analytical solution of the DGLAP equation up to NNLO. [...]

NNLO predictions for dijet production in diffractive DIS
25th International Workshop on Deep Inelastic Scattering and Related Topics, DIS2017, Meeting locationBirmingham, United Kingdom, 3 Apr 2017 - 7 Apr 20172017-04-032017-04-07 Proceedings of Science (DIS2017), 073 (2017) [10.3204/PUBDB-2017-12499]  GO

AbstractCross sections for inclusive dijet production in diffractive deep-inelastic scattering are calculated for the first time in next-to-next-to-leading order (NNLO) accuracy.These cross sections are compared to several HERA measurements published by the H1 and ZEUS collaborations.We computed the total cross sections, 49 single-differential and five double-differential distributions for six HERA measurements.The NNLO corrections are found to be large and positive.The normalization of the resulting predictions typically exceeds the data, while the kinematical shape of the data is described better at NNLO than at next-to-leading order (NLO).Our results use the currently available NLO diffractive parton distributions, and the discrepancy in normalization highlights the need for a consistent determination of these distributions at NNLO accuracy..

Searches for low mass beyond the Standard Model (BSM) particles using the discovered Higgs boson at 125 GeV are presented in different possible channels, including invisible decays of the Higgs boson, the Higgs boson decays to new light bosons in which the light bosons decay to SM particles, and Lepton Flavour Violation (LFV) of the Higgs boson. The data is collected with the CMS detector at the LHC which corresponding to integrated luminosities of 19.7 and 2.3 fb$^{−1}$ at central-of-mass energies of 8 and 13 TeV, respectively [...]

Higgs boson measurements and extended scalar sector searches in fermionic final states
25th International Workshop on Deep Inelastic Scattering and Related Topics, DIS2017, Meeting locationBirmingham, United Kingdom, 3 Apr 2017 - 7 Apr 20172017-04-032017-04-07 Proceedings of Science (DIS2017), 277 (2017) [10.3204/PUBDB-2017-12495]  GO

Since the discovery of the Higgs boson in the year 2012, the CMS experiment continuously makes use of a variety of final states to measure the properties of the Higgs boson, as well as to search for it in final states where the discovery could not yet be established. This article concentrates on Higgs searches in fermionic final states including a search for the Standard Model Higgs boson in the H → $b\bar{b}$ channel. [...]

The high-precision HERA data allow searches for "beyond the Standard Model" contributions to electron-quark scattering up to TeV scales. Combined H1 and ZEUS measurements of inclusive deep inelastic cross sections in neutral and charged current ep scattering are considered, corresponding to a luminosity of around 1 fb$^{−1}$. [...]

Measurements of open beauty and charm production cross sections in deep inelastic ep scattering at HERA from the H1 and ZEUS Collaborations are combined. Reduced cross sections for beauty and charm production are obtained in the kinematic range of photon virtuality 2.5≤Q2≤2000 GeV2 and Bjorken scaling variable 3×10−5≤xBj≤5×10−2.The combination method accounts for the correlations of the statistical and systematic uncertainties among the different data sets.
