Proton Structure from ep and pp
Oral Presentation
Isolated prompt photons provide a direct probe of short-
distance physics, complementary to that provided by measurements of
jets or vector-bosons and are sensitive to the gluon density of the
proton. The inclusive prompt photon cross sections have been measured
by the ATLAS collaboration at various centre-of-mass energies of pp
collisions over a wide range of transverse momenta. These...

Proton Structure from ep and pp
Oral Presentation
A combination is presented of all inclusive deep inelastic cross sections previously published by the H1 and ZEUS collaborations at HERA for neutral and charged current ep scattering for zero beam polarisation. The data correspond to an integrated luminosity of about 1 fb^-1 and span six orders of magnitude in negative four-momentum-transfer squared, Q2, and Bjorken x. The correlations of the...

Proton Structure from ep and pp
Oral Presentation
Several measurements performed by the ATLAS collaboration
are either useful to constrain the proton structure or are affected by
its associated uncertainties.
Measurements of the W+c production and the inclusive W and Z
differential cross sections are found to constrain the poorly known
strange-quark density at low x. Similarly, the ratio of W+/W-
production is found to constrain the...

Proton Structure from ep and pp
Oral Presentation
The uncertainties of protons parton distribution functions (PDFs) play a dominant role for the precision tests of the Standard Model (SM) and they also impact substantially the theory predictions of Beyond SM high mass production. We present theHERAFitter project which provides a unique open-source software framework for the determination of the proton's PDFs and for the interpretation of the...

Proton Structure from ep and pp
Oral Presentation
The current PDF4LHC recommendation to estimate uncertainties due to
parton distribution functions (PDFs) in theoretical predictions for LHC
processes involves the combination of separate predictions computed
using PDF sets from different groups, each of which comprises a
relatively large number of either Hessian eigenvectors or Monte Carlo
(MC) replicas. We present a strategy for the...

Proton Structure from ep and pp
Oral Presentation
H1 and ZEUS have published single-differential cross sections for inclusive D* meson production in deep-inelastic ep scattering at HERA from their respective final data sets. These cross sections are combined in the common visible phase space region of photon virtuality Q^2 > 5 GeV^2, electron inelasticity 0.02 < y < 0.7 and the D* meson's transverse momentum p_T (D*)> 1.5 GeV and...

Proton Structure from ep and pp
Oral Presentation
Inclusive hadron production cross sections and angular distributions in
e+e- collisions shed light on fundamental questions of hadronization and fragmentation processes. We present measurements of the Collins azimuthal asymmetries in inclusive production of hadron pairs, in the e+e- -> h1 h2 X annihilation process, where the hadrons (either kaons or pions) are produced in opposite...
