Theoretical calculations for jet substructure observables with accuracy beyond leading-logarithm have recently become available. Such observables are significant not only for probing a new regime of QCD at a hadron collider, but also for improving the understanding of jet substructure properties that are used in many searches for physics beyond the Standard Model. In this talk, we present...
Precision measurements of the production cross sections of W and Z bosons in proton-proton collisions provide stringent tests of perturbative QCD and yield important information about the parton distribution functions (PDFs) for quarks within the proton. We report measurements of fiducial integrated and differential cross sections for inclusive W+, W- and Z boson production, analysed in the...
The lepton angular distributions of the Drell-Yan process in fixed-target experiments and the Z-boson production at colliders are investigated by an intuitive geometric approach together with perturbative QCD calculations. We show that the main features of the kinematic dependencies of the lepton angular distributions can be well understood in the geometrical approach. Implications of this...
The IceCube Neutrino Observatory, located at the South Pole, is a
Cherenkov detector that continuously monitors a cubic kilometer of instrumented glacial ice for neutrino interactions in the sub-TeV to EeV energy range. Its
primary design goal is the study of powerful astrophysical objects
that could act as natural particle accelerators and thus as sources of
(ultra) high energy cosmic...
The production of prompt isolated photons at hadron colliders provides stringent tests of perturbative QCD and can be used to evaluate probability density functions of partons in the proton. In this talk, we present the measurements of the isolated-photon plus two jets and the inclusive isolated-photons cross sections, both measured using proton-proton collision data collected by the ATLAS...
Measurements of weak boson production in association with jets are presented. First, differential cross sections for Z-boson and W-boson production in association with jets are presented, with the measurements performed using proton-proton collisions at √s = 8 TeV. The data are compared to next-to-leading order QCD calculations and predictions from a variety of different parton distribution...
