We consider the elastic scatterings between the incident heavy-quark and the thermal partons with both hard and soft momentum transfers. Our results show that the heavy-quark energy loss is significantly suppressed in the semi-quark-gluon plasma due to a background field that is self-consistently generated in the effective theory. On the other hand, the suppression strongly depends on the temperature of the plasma which becomes negligible above 2~3 times the critical temperature. For a realistic coupling constant, ignoring a relatively weak dependence on the heavy-quark velocity, the suppression on the collisional energy loss can be approximated by an overall factor determined solely by the background field.", "revisions": [ { "version": "v1", "updated": "2024-02-28T02:36:15.000Z" } ], "analyses": { "keywords": [ "collisional energy loss", "semi-quark-gluon plasma", "background field effective theory", "heavy-quark energy loss", "soft momentum transfers" ], "note": { "typesetting": "TeX", "pages": 17, "language": "en", "license": "arXiv", "status": "editable" } } }
