A search for tt resonances in lepton+jets events with highly boosted top quarks collected in pp collisions at √s = 7TeV with the ATLAS detector [PDF]

open access: yes, 2012
A search for resonant production of high-mass top-quark pairs is performed on 2.05 fb -1 of proton-proton collisions at √s = 7 TeV collected in 2011 with the ATLAS experiment at the Large Hadron Collider.

Early EM fields in PbPb collisions via their effect on dimuon decays of Z bosons and top quark production with CMS [PDF]

open access: yesEPJ Web of Conferences
In this article, we discuss a selection of measurements of initial-state probes conducted by CMS, the Z boson and top quark, to study early-stage aspects of heavy ion collisions.

Two-loop helicity amplitudes for diphoton production with massive quark loop

open access: yesJournal of High Energy Physics
We compute two-loop helicity amplitudes in QCD for diphoton production through quark- and gluon-initiated channels, accounting for a massive internal quark loop by keeping its full mass dependence.

Multiparticle production at mid-rapidity in the color-glass condensate

open access: yesJournal of High Energy Physics, 2019
In this paper, we compute a number of cross sections for the production of multiple particles at mid-rapidity in the semi-dilute / dense regime of the color-glass condensate (CGC) effective field theory.

Phenomenological aspects of an anisotropic quark-gluon plasma

open access: yes, 2010
In this work we investigate phenomenological aspects of an anisotropic quark-gluon plasma. In the first part of this thesis, we formulate phenomenologicalmodels that take into account the momentumspace anisotropy of the system developed during the ...

Heavy quark production at HERA

open access: yesFizika B : a journal of experimental and theoretical physics, 2008
Recent measurements of the charm and beauty production in ep collisions at HERA are presented. Heavy-quark tagging methods used by the ZEUS and H1 experiments are described. Cross section results are compared with NLO QCD predictions and in general the data are well described by the calculations. A determination of the charm and beauty contributions to

Monte Carlo Simulations of Heavy Particles for the Large Hadron Collider [PDF]

open access: yes, 2013
As the Large Hadron Collider has switched on at CERN in Geneva, accurate predictions for complex hadronic processes are essential for the validation of theory and therefore the success of the machine.

Heavy Quark Production in QCD [PDF]

open access: yes, 1988
In this paper I review the status of the theory of heavy quark production. The production of heavy quarks in hadron-hadron and photon-hadron collisions continues to be a topic of great theoretical interest. The reasons for this enthusiasm are the existence of experimental data on charm production and the recent publication of data on bottom quark ...
