Lattice study of classical inflaton decay

Tomislav Prokopec, Thomas G. Roos

We study numerically the decay of the inflaton by solving the full non-linear equations of motion on the lattice. We confirm that parametric resonance is effective in transferring…

Some aspects of thermal inflation: the finite temperature potential and topological defects

Tiago Barreiro, E. J. Copeland, David H. Lyth +1

Currently favoured extensions of the Standard Model typically contain `flaton fields' defined as fields with large vacuum expectation values (vevs) and almost flat potentials. If a…

CKM Favored Semileptonic Decays of Heavy Hadrons at Zero Recoil

Tung-Mow Yan, Hai-Yang Cheng, Hoi-Lai Yu

We study the properties of Cabibbo-Kobayashi-Maskawa (CKM) favored semileptonic decays of mesons and baryons containing a heavy quark at the point of no recoil. We first use a diag…

The Impossibility of Baryogenesis at a Second Order Electroweak Phase Transition

Tomislav Prokopec, Robert Brandenberger, Anne-Christine Davis

We investigate whether baryogenesis is possible at a second order electroweak phase transition. We find that under rather general conditions, the departure from thermal equilibrium…

Hadronic Light-by-light Scattering Contribution to Muon

M. Hayakawa, T. Kinoshita, A. I. Sanda

The hadronic light-by-light scattering contribution to muon is examined based on the low energy effective theories of QCD, the Nambu-Jona-Lasinio model and hidden local symme…

Large Universality of The Baryon Isgur--Wise Form Factor: The Group Theoretical Approach

Chi-Keung Chow

In a previous article, it has been proved under the framework of chiral soliton model that the same Isgur--Wise form factor describes the semileptonic and $Σ^{(*)}_b\to…
