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...
Measurements of inclusive jet cross sections have been performed by a number of experiments in proton—proton, proton—anti-proton, and electron—proton collisions and at different center-of-mass energies. Since inclusive jets are directly sensitive to the strong coupling constant, and exhibit a high sensitivity to the gluon content of the proton, a thorough understanding of the available...
We present measurements of multi-differential Jet cross sections over a wide range in transverse momenta from inclusive jets to multi-jet final states. We present studies on the impact these measurements have on the determination of the strong coupling alphas as well as on parton density functions.
The production of inclusive jets and di-jets at hadron colliders provides a stringent test of perturbative QCD at the highest energies. The process can also be used to probe the gluon density function of the proton.
The ATLAS collaboration has measured the inclusive jet production cross section in 20.3 /fb of data collected at a center-of-mass energy of 8TeV and in 3.2 /fb of data...
The production of prompt isolated photons at hadron colliders provides a stringent test of perturbative QCD and can be used to probe the gluon density function of the proton.
The ATLAS collaboration has performed precise measurements of the inclusive production of isolated prompt photons at a center-of-mass energy of 13 TeV, differential in both rapidity and the photon transverse momentum. In...
The LHC has recently precise measurements of the transverse momentum
of the $Z$ boson that provide a unique constraint on the structure of the
proton. Recent theoretical developments have allowed the calculation of these
process at next-to-next-to-leading order. In this talk theoretical fixed-order
predictions for this data are presented and their impact on the determination
of PDFs is described.
Measurements of the Drell-Yan production of W and Z/gamma bosons at the LHC provide a benchmark of our understanding of perturbative QCD and probe the proton structure in a unique way. The ATLAS collaboration has performed new high precision measurements at a center-of-mass energies of 7 and 13 TeV. The measurements are performed for W+, W- and Z/gamma bosons integrated and as a function of...
LHCb, while purpose built for b-physics, also functions as a general purpose forward detector, covering the pseudo-rapidity range 2.0 to 5.0. This has allowed performing several measurements concerning the production of W, Z and top. A selection of these results will be presented, highlighting the scope of the LHCb physics programme.
We consider the production of inclusive W bosons in variety of high-energy hadronic collisions: p-p, p-p$\overline{\rm p}$, p-Pb, and Pb-Pb. In particular, we focus on the resulting distributions of charged leptons from W decay that can be measured with relatively low backgrounds. The leading-order expressions within the collinearly factorized QCD indicate that the c.m. energy dependence at...

Measurement of the kt splitting scales in Z events with the ATLAS detector
While properties of the jets are typically directly using the jet momenta, we present here a complementary approach, studying the jet production rates at different resolution scales. In...
