Thermal Abundances of Heavy Particles
Matsumoto and Yoshimura [hep-ph/9910393] have argued that there are loop corrections to the number density of heavy particles (in thermal equilibrium with a gas of light particles) that are not Boltzmann suppressed by a factor of e at temperatures T well below the mass M of the heavy particle. We argue that this conclusion follows from an inappropriate definition of the number density of the he...
متن کاملHeavy Particles from Inflation
We describe a simple and efficient mechanism by which very heavy particles are copiously created from a primordial inflationary epoch. It works for scalar fields which are massless or very light during inflation and acquire a large mass right after the end of inflation. Such particles can exist in realistic scenarios, as we illustrate with several examples in the context of both field and strin...
متن کاملMutagenic effects of heavy charged particles.
Heavy charged particles constitute the most important radiation risk in space. Since mutations can give rise to cancer the investigation of their induction may be helpful for risk quantification. This paper describes experiments in a number of mammalian cells performed with a large range of linear energy transfer (LET). RBE values are always found to increase with LET up to about 100 keV/microm...
متن کاملsolidification/stabilization of heavy metals from air heater washing wastewater treatment in thermal power plants
in the present investigation, for the first time in iran, dewatered sludge waste from air heater washing wastewater treatment of a thermal power plant was subjected to investigation of the cement base stabilization and solidification experiments in order to reduce the mobility of heavy and other hazardous metals as well as increasing the compressive strength of the solidified product for possib...
متن کاملThermal instability effects in SiC Power MOSFETs
Silicon carbide (SiC) power MOSFETs are characterised by potentially thermally unstable behaviour over a broad range of bias conditions. In the past, such behaviour has been shown for silicon (Si) MOSFETs to be related to a reduction of Safe Operating Area at higher drain–source bias voltages. For SiC MOSFETs no characterisation exists yet. This paper presents a thorough experimental investigat...
