| Popis: | We give the modification of formulas for $p_{\perp}$-broadening and energy loss which are necessary to calculate parton interactions in a medium with flow. Arguments are presented leading to the conclusion that for large $p_{\perp}$-spectra observed in heavy ion collisions at RHIC, the influence of transverse flow on the determination of the "quenching power" of the produced medium is small. This leaves open the question of the interpretation of data in a consistent perturbative framework. 8 pages and 4 figures; version v2 includes more consistent notations and correction of fig.2; version v3 contains a misprint correction, an added sentence in section 3C and in the Introduction as well as in section 4 a rephrasing of comments about references [31,32,35] |
