Parallel Session III: EM Probes (III)
- Axel Drees
Dileptons are able to traverse a strongly interacting medium with minimal interactions and thus are excellent probes of the hot, dense, and strongly interacting medium created in relativistic heavy-ion collisions. For the dileptons with an invariant mass less than ~1.2 GeV/c$^{2}$, the production is predominately from vector-meson decays. Information about any in-medium modifications of the...
W and Z bosons are short lived and do not interact strongly. Thus their production yields, observed via dilepton decay channels in proton-lead and lead-lead collisions, provide direct tests of both binary collision scaling and the nuclear modification of parton distribution functions (nPDF). Proton-lead collisions further provide an excellent opportunity to test nPDFs. The ATLAS detector...
The production of massive vector boson ($W^{\pm}/Z^0$), is an excellent probe of the cold nuclear medium effect, and can provide useful constraints on the nuclear parton distribution (nPDFs), in heavy-ion collisions at the LHC and the future colliders with much higher energies.
Within the framework of perturbative QCD, we systematically study the vector boson production in p+Pb and Pb+Pb...
In this contribution I will talk about our recent results on photon production from the Color Glass Condensate (CGC) in the high energy pA collision. The nucleus is considered as a dense source of soft gluons while the proton is more dilute. This allows a systematic expansion of the amplitude in the powers of the gluon density of the proton.
The zeroth order approximation comes from...
