Torres2012-02-25T14:53:03Z20110003-491http://www.repositorio.ufba.br/ri/handle/ri/5446v. 326.texto completo: acesso restrito. p.2737–2772.We compute the charm drag and diffusion coefficients in a hot pion gas, such as is formed in a heavy ion collision after the system cools sufficiently to transit into the hadron phase. We fully exploit heavy quark effective theory (with both D and D∗ mesons as elementary degrees of freedom during the collision) and chiral perturbation theory, and employ standard unitarization to reach higher temperatures. We find that a certain friction and shear diffusion coefficients are almost p2-independent at a fixed temperature which simplifies phenomenological analysis. At the higher end of reliability of our calculation, T ≃ 150 MeV, we report a charm relaxation length λc ≃ 40 fm, in agreement with the model estimate of He, Fries and Rapp. The momentum of a 1 GeV charm quark decreases about 50 MeV per fermi when crossing the hadron phase.Submitted by Ana Valéria de Jesus Moura (anavaleria_131@hotmail.com) on 2012-02-25T14:53:03Z No. of bitstreams: 1 nps59.tmp.pdf: 692410 bytes, checksum: aac2f6cdfe4d978db2323fb021602a49 (MD5)Made available in DSpace on 2012-02-25T14:53:03Z (GMT).
