Classical fields as coherent states and diffusion equations
Jukka Sirkka, Iiro Vilja
We present a derivation of the effect of the classical field configuration to the diffusion equations. Using the formalism of the thermo field dynamics we propose a systematic and…
On the phenomenology of a Z' coupling only to third-family fermions
A. A. Andrianov, P. Osland, A. A. Pankov +2
The phenomenology of an additional U(1) neutral gauge boson Z' coupled to the third family of fermions is discussed. One might expect such a particle to contribute to processes whe…
Damping rate of neutrinos in the singlet Majoron model
Timo Holopainen, Jukka Maalampi, Jukka Sirkka +1
The damping rate and free path of neutrinos in the singlet Majoron model have been calculated including both finite temperature and symmetry breaking effects. The behaviour of righ…
Updated Parameter Limits of the Left-Right Symmetric Model
J. Sirkka
Bounds of the neutral current sector parameters of the left-right symmetric model are investigated taking into account the low-energy data, LEP-data and CDF-result for the top mass…
Baryon and lepton number transport in electroweak phase transition
J. Maalampi, J. Sirkka, I. Vilja
We consider the baryon number generation by charge transport mechanism in the electroweak phase transition taking properly into account thermal fluxes through the wall separating t…
Vacuum stability in the singlet Majoron model
J. Sirkka, I. Vilja
We study the vacuum stability of the singlet Majoron model using full renormalization group improved scalar potential and Monte Carlo techniques. We show that in the perturbative r…
Unitarity of the Standard Model at the Higgs' Resonance
J. Sirkka, I. Vilja
We compute a unitarity bound for higgs mass using one--loop corrected s--wave partial amplitude for scattering. We use the equivalence theorem and sho…
Chemical equilibrium in QCD gas in the early universe
Kari Enqvist, Jukka Sirkka
We compute the thermally averaged $\qq$--annihilation rate into two and three gluons in the early universe. We show that at very high temperatures $\qq\to ggg$ represents only a 3\…
