Measurement of beauty production via non-prompt charm hadrons in p–Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The production cross sections of D0, D+, and Λ c + $$ {\Lambda}_{\textrm{c}}^{+} $$ hadrons originating from beauty-hadron decays (i.e. non-prompt) were measured for the first time at midrapidity in proton–lead (p–Pb) collisions at the center-of-mass ...

Ausbreitung von Jets und Entstehung von Machkegeln in (3+1) dimensionaler idealer Hydrodynamik

open access: yes, 2009
This thesis investigates the jet-medium interactions in a Quark-Gluon Plasma using a hydrodynamical model. Such a Quark-Gluon Plasma represents a very early stage of our universe and is assumed to be created in heavy-ion collisions.

Single leptons from heavy quark production [PDF]

open access: yes, 1987
We consider the single lepton decay mode of heavy quarks as a signature of heavy quark pair production at the SSC. We find that events with multijets (n/sub jet/ greater than or equal to 3) and a single high p/sub T/ lepton are a good signal for heavy ...

Heavy Quark Production at High Energy

open access: yes, 2001
We report on QCD radiative corrections to heavy quark production valid at high energy. The formulae presented will allow a matched calculation of the total cross section which is correct at $O(\as^3)$ and includes resummation of all terms of order $\as^3

Direkte Photonen in Schwerionenkollisionen

open access: yes, 2011
Direct photon emission from heavy-ion collisions has been calculated and compared to available experimental data. Three different models have been combined to extract direct photons from different environments in a heavy-ion collision: Thermal photons ...

Prompt and non-prompt J/ψ production at midrapidity in Pb–Pb collisions at s NN $$ \sqrt{s_{\textrm{NN}}} $$ = 5.02 TeV

open access: yesJournal of High Energy Physics
The transverse momentum (p T) and centrality dependence of the nuclear modification factor R AA of prompt and non-prompt J/ψ, the latter originating from the weak decays of beauty hadrons, have been measured by the ALICE collaboration in Pb–Pb collisions

Study of the ZZ diboson production at CDF II [PDF]

open access: yes, 2013
The subject of this Thesis is the production of a pair of massive Z vector bosons in the proton antiproton collisions at the Tevatron, at the center-of-mass energy sqrt(s) = 1.96 TeV.

Heavy quark production in deep inelastic electron-nucleus scattering

open access: yes, 2010
Heavy quark production has been very well studied over the last years both theoretically and experimentally. Theory has been used to study heavy quark production in ep collisions at HERA, in pp collisions at Tevatron and RHIC, in pA and dA collisions at ...

Untersuchung von Phänomenen bei hohen Transversalimpulsen im Rahmen eines partonischen Transportmodells

open access: yes, 2011
In the work presented herein the microscopic transport model BAMPS (Boltzmann Approach to Multi-Parton Scatterings) is applied to simulate the time evolution of the hot partonic medium that is created in Au+Au collisions at the Relativistic Heavy Ion ...
