Towards understanding thermal history of the Universe through direct and indirect detection of dark matter
Leszek Roszkowski, Sebastian Trojanowski, Krzysztof Turzynski
We examine the question to what extent prospective detection of dark matter by direct and indirect- detection experiments could shed light on what fraction of dark matter was gener…
Axino dark matter with low reheating temperature
Leszek Roszkowski, Sebastian Trojanowski, Krzysztof Turzynski
We examine axino dark matter in the regime of a low reheating temperature T_R after inflation and taking into account that reheating is a non-instantaneous process. This can have a…
Neutralino and gravitino dark matter with low reheating temperature
Leszek Roszkowski, Sebastian Trojanowski, Krzysztof Turzynski
We examine a scenario in which the reheating temperature after inflation is so low that it is comparable to, or lower than, the freeze out temperature of ordinary WIMPs. In t…
Gravitino dark matter with constraints from Higgs boson mass and sneutrino decays
Leszek Roszkowski, Sebastian Trojanowski, Krzysztof Turzynski +1
We investigate gravitino dark matter produced thermally at high temperatures and in decays of a long-lived sneutrino. We consider the Non-Universal Higgs Model and a generalized ga…
On low-energy predictions of unification models inspired by F-theory
Tomasz Jelinski, Jacek Pawelczyk, Krzysztof Turzynski
The aim of this paper is to discuss phenomenological consequences of a particular unification model (Z_3 model) inspired by F-theory. The most distinctive feature of this model is…
Supersymmetric mass spectra for gravitino dark matter with a high reheating temperature
Laura Covi, Marek Olechowski, Stefan Pokorski +2
Supersymmetric theories with gravitino dark matter generally do not allow the high reheating temperature required by thermal leptogenesis without running afoul of relic abundance o…
Reheating Temperature and Gauge Mediation Models of Supersymmetry Breaking
Marek Olechowski, Stefan Pokorski, Krzysztof Turzynski +1
For supersymmetric theories with gravitino dark matter, the maximal reheating temperature consistent with big bang nucleosynthesis bounds arises when the physical gaugino masses ar…
Gravity in Gauge Mediation
Zygmunt Lalak, Stefan Pokorski, Krzysztof Turzynski
We investigate O'Raifeartaigh-type models for F-term supersymmetry breaking in gauge mediation scenarios in the presence of gravity. It is pointed out that the vacuum structure of…
Flavour physics of leptons and dipole moments
M. Raidal, A. van der Schaaf, I. Bigi +82
This chapter of the report of the ``Flavour in the era of the LHC'' Workshop discusses the theoretical, phenomenological and experimental issues related to flavour phenomena in the…
Quasi-degenerate neutrinos and leptogenesis from L_mu-L_tau
E. J. Chun, K. Turzynski
We provide a framework for quasi-degenerate neutrinos consistent with a successful leptogenesis, based on the L_mu-L_tau flavor symmetry and its breaking pattern. In this scheme, a…
Decoupling, lepton flavour violation and leptogenesis
Krzysztof Turzynski
Several classes of neutrino mass models, which can naturally account for hierarchical masses and the bi-large pattern of neutrino mixing, are constructed from a bottom-up perspecti…
Low-scale standard supersymmetric leptogenesis
Martti Raidal, Alessandro Strumia, Krzysztof Turzynski
Strictly adhering to the standard supersymmetric seesaw mechanism, we present a neutrino mass model which allows successful standard thermal leptogenesis compatible with gravitino…
Patterns of Lepton-Flavour Violation Motivated by Decoupling and Sneutrino Inflation
Piotr H. Chankowski, John Ellis, Stefan Pokorski +2
We present predictions for flavour-violating charged-lepton decays induced by the seesaw mechanism implemented within the constrained minimal supersymmetric standard model (CMSSM)…
Degenerate minimal see-saw and leptogenesis
Krzysztof Turzynski
We analyze the most general version of the supersymmetric minimal see-saw model with only two right-chiral neutrinos which are degenerate in masses at the scale of Grand Unificatio…
Limits on for thermal leptogenesis with hierarchical neutrino masses
P. H. Chankowski, K. Turzynski
We make a simple observation that if one of the right-chiral neutrinos is very heavy or its Yukawa couplings to the standard lepton doublets are negligible, so that it effectively…
On suppressing the Higgsino-mediated proton decay in SUSY SO(10) GUT's
Krzysztof Turzynski
Using the freedom in SO(10) GUT's one can generalize the existing models without changing the mass spectrum of fermions to obtain a significant suppression of proton decay resultin…
