Dynamical Problems of Baryogenesis

  • John M. Cornwall


Above a certain temperature T c any non-Abelian gauge theory has a strongly-coupled sector, consisting of the three-dimensional magnetic gauge fields. We argue that in this sector the electroweak part of the standard model develops an entropy-dominated condensates of Z 2 strings, and that associated with those strings is a strongly-fluctuating Chern-Simons condensate driven by the strings’ linking, twisting, and writhing. (For SU(N) gauge groups with N≥3 there are links with trivalent vertices; these vertices also give rise to Chern-Simons fluctuations.) Similar phenomena happen for QCD; we discuss the effects of these, as well as QCD sphalerons, on baryogenesis. We outline an ongoing program, including study of the reaction of preexisting Chern-Simons condensates on the strings and sphalerons, and the problem of finding the non-perturbative electroweak free energy near the phase transition.

    The gauge and Higgs field configuration making up a sphaleron was first constructed by Dashen, Hasslacher, and Neveu (Phys. Rev. D10, 4138 (1974)), but not interpreted topologically. This was rediscovered and shown to interpolate topological charge by Manton and Klinkhamer (N. Manton, Phys. Rev. D28, 2019 (1983); F. Klinkhamer and N. Manton, ibid. 30, 2212 (1984)).Google Scholar

The QCD sphaleron was presented as a glueball, with no interpretation of its connection to the axial anomaly. Eq. (19) of this reference is a misprint.Google Scholar

    The calculation of Ref. 4 was felt by the author not to be highly accurate, so he requested someone to recalculate it, and the new answer was claimed to have a coefficient 3.1 in place of 5.3. This (erroneous) value was quoted in Ref. 12 and elsewhere, unfortunately.Google Scholar

    Compare to the situation with fractional instantons (J. M. Cornwall and G. Tiktopoulos, Phys. Lett. B181, 353 (1986)). Two instantons, each carrying fractional charge but with integral total charge, must be joined by a sphaleronlike world line which is not detectable from the sphere at infinity, but an isolated fractional instanton would have the sphaleron branch line running all the way to infinity.Google Scholar
