Fermion fluctuation determinant and the sphaleron bound
- Princeton University, Joseph Henry Laboratories, PO Box 708, Princeton, New Jersey 08544 (United States)
We investigate analytically the fermionic fluctuation determinant at finite temperatures in the minimal standard model, including all operators up to dimension 6 and all contributions to the effective potential to all orders in the high {ital T} expansion, to 1 loop. We apply the results to find corrections to the sphaleron erasure rate in the broken phase. We conclude that the analytic treatment of fermions is very reliable and that there is a great deal of baryon erasure after the phase transition for any physical Higgs mass. {copyright} {ital 1996 The American Physical Society.}
