Higgs boson production at the LHC: Transverse-momentum resummation and rapidity dependence
(Elsevier Science, 2008-03)
We consider Higgs boson production by gluon fusion in hadron collisions. We study the doubly-differential transverse-momentum (qT) and rapidity (y) distribution of the Higgs boson in perturbative QCD. In the region of small ...
Production of Drell-Yan lepton pairs in hadron collisions: Transverse-momentum resummation at next-to-next-to-leading logarithmic accuracy
(Elsevier Science, 2011-01)
We consider the transverse-momentum (qT) distribution of Drell-Yan lepton pairs produced in hadron collisions. At small values of qT, we resum the logarithmically-enhanced perturbative QCD contributions up to next-to-nex ...
Experimental verification of position-dependent angular-momentum selection rules for absorption of twisted light by a bound electron
(IOP Publishing, 2018-02)
We analyze the multipole excitation of atoms with twisted light, i.e, by a vortex light field that carries orbital angular momentum. A single trapped 40Ca+ ion serves as a localized and positioned probe of the exciting ...
The Structure of Non-leading Logarithmic Corrections at Small Transverse Momentum in Hadronic Collisions
(Elsevier Science, 2001-11)
We consider the region of small transverse momenta in the production of high-mass systems in hadronic collisions. By using the current knowledge on the infrared behaviour of tree-level and one- loop QCD amplitudes at ...
Search for dark matter in events with heavy quarks and missing transverse momentum in $pp$ collisions with the ATLAS detector
(Springer, 2015-02)
This article reports on a search for dark matter pair production in association with bottom or top quarks in 20.3 fb−1 of pp collisions collected at s√=8 TeV by the ATLAS detector at the LHC. Events with large missing ...
Search for large missing transverse momentum in association with one top-quark in proton-proton collisions at s√ = 13 TeV with the ATLAS detector
(Springer, 2018-12)
This paper describes a search for events with one top-quark and large missing transverse momentum in the final state. Data collected during 2015 and 2016 by the ATLAS experiment from 13 TeV proton?proton collisions at the ...
Search for dark matter at s√=13 TeV in final states containing an energetic photon and large missing transverse momentum with the ATLAS detector
(Springer, 2017-06)
Results of a search for physics beyond the Standard Model in events containing an energetic photon and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. As the number of ...
Measurement of the Jet Size Dependence of Inclusive Jet Suppression in Lead-Lead Collisions at √sNN = 2.76 TeV with the ATLAS Detector
(Elsevier Science, 2013-02)
Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at √ sNN = 2.76 TeV corresponding to an integrated ...
Jet size dependence of single jet suppression in lead-lead collisions at sqrt(s(NN)) = 2.76 TeV with the ATLAS detector at the LHC
(Elsevier Science, 2013-01)
Measurements of inclusive jet suppression in heavy ion collisions at the LHC provide direct sensitivity to the physics of jet quenching. In a sample of lead-lead collisions at sqrt(s) = 2.76 TeV corresponding to an integrated ...
Measurement of jet fragmentation in Pb+Pb and pp collisions at sNN−−−√=2.76 TeV with the ATLAS detector at the LHC
(Springer, 2017-02)
The distributions of transverse momentum and longitudinal momentum fraction of charged particles in jets are measured in Pb+Pb and pp collisions with the ATLAS detector at the LHC. The distributions are measured as a ...
