Scenarios for electroweak baryogenesis require an understanding of the effective potential at finite temperature near a first-order electroweak phase transition. Working in Landau gauge, we present a calculation of the dominant two-loop corrections to the ring-improved one-loop potential in the formal limit g 4 â‰ª Î» â‰ª g 2 , where Î» is the Higgs self-couplingâ€¦ (More)

Topological analysis of the experimental electron density rho(r) in hydrogen-bonding regions has been carried out for a large number of organic compounds using different multipole models and techniques. Relevant systematic relationships between topological properties at the critical points and the usual geometric parameters are pointed out. Resultsâ€¦ (More)
