Recently Garcia Bellido et. al. have proposed that electroweak baryogenesis may occur at the end of inflation, in a scenario where the reheat temperature is too low for electroweak symmetry restoration. I show why the scenario is difficult to test reliably by classical field techniques on the lattice.

Helical coil heat exchangers are widely used in industrial applications ranging fromcryogenic processes, air-conditioning, and nuclear reactors to waste heat recovery due totheir compact size and high heat transfer coefficient. In this kind of heat exchangers, flowand heat transfer are complicated. This paper reports a numerical investigation of theinfluence of different parameters such as coil...

Thermal leptogenesis is an attractive mechanism for generating the baryon asymmetry of the Universe. However, in supersymmetric models, the parameter space is severely restricted by the gravitino bound on the reheat temperature TRH . Using a parametrisation of the seesaw in terms of left-handed inputs, which are related to weak-scale observables in mSUGRA, the low-energy footprints of thermal l...

For many years radiation thermometers have been used to make non-contact temperature measurements of hot objects, particularly in industrial situations such as reformer furnaces, steel reheat furnaces, and ceramics kilns. They occupy an important niche in temperature measurement since any other type of thermometer would have very slim chances of surviving in these and other such hostile environ...
