Torres2014-09-09T14:44:54Z20130375-9474http://repositorio.ufba.br/ri/handle/ri/15880v. 914Texto completo: acesso restrito. p. 505–511Charm and bottom transport coefficients in a medium constituted of light mesons, such as is formed in the hadronic phase of heavy-ion collisions, are obtained within an effective field theory approach implementing heavy-quark symmetry and chiral symmetry breaking. Heavy flavor propagates in the medium as D/BD/B and D⁎/B⁎D⁎/B⁎ degrees of freedom, and unitarization of the lowest order heavy–light meson amplitudes is used in order to reach high temperatures. The latter accounts for dynamically generated resonances in isospin 1/2 channels, a feature that leads to a more efficient heavy-flavor diffusion. We discuss the temperature and momentum dependence of the friction and diffusion coefficients in a transport approach up to temperatures of about T≃150 MeVT≃150 MeV, and provide estimates of the charm/bottom relaxation lengths and momentum loss. Implications for heavy-meson spectrum observables in heavy-ion collisions are discussed.Submitted by Suelen Reis (suziy.ellen@gmail.com) on 2014-05-06T16:40:46Z No. of bitstreams: 1 1-s2.0-S0375947413003382-main.pdf: 154394 bytes, checksum: f1d2f6e2c1e469851eac9706c8a7d1b0 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2014-09-09T14:44:54Z (GMT) No. of bitstreams: 1 1-s2.0-S0375947413003382-main.pdf: 154394 bytes, checksum: f1d2f6e2c1e469851eac9706c8a7d1b0 (MD5)Made available in DSpace on 2014-09-09T14:44:54Z (GMT).
