On The medium-modified g→cc¯ splitting function in the BDMPS-Z formalism
Seminar
|
Abstract: The formalism of Baier-Dokshitzer-Mueller-Peigné-Schiff and Zakharov (BDMPS-Z) determines modifications of parton splittings in the QCD plasma that arise from medium-induced gluon radiation. Here, we extend the BDMPS-Z formalism to medium-modifications of the gluon splitting into two massive charm quarks. We derive a compact path-integral formulation that resums effects from arbitrary many interactions with the medium. We identify two qualitatively different phenomena: a medium-induced momentum broadening that increases the invariant mass of quark-anti-quark pair and a medium-enhanced production of such pairs. https://arxiv.org/abs/2203.11241 This seminar will take place at Sala de Xuntas and will be streamed on Zoom https://zoom.us/j/97561282565?pwd=eE1mSFNqcnpL Meeting ID: 975 6128 2565 Passcode: 738971 |
