Multi-Instanton Corrections to Superpotentials in Type II Compactifications
Tomasz Jelinski, Jacek Pawelczyk
We consider two simple examples of multi-instanton configurations in type II 4d N=1 superstring compactifications. The first one involves O(1) and U(1) D2-instantons embedded in T^…
Gauge Symmetry Breaking in a Throat Geometry
Jacek Pawełczyk
We analyze behaviour of D3-branes in BGMPZ throat geometry. We show that although single brane has some of the moduli stabilized multi-brane system tends to expand and form a bound…
Phase Transitions in NJL and super-NJL models
Z. Lalak, J. Pawelczyk, S. Pokorski
An elementary method of determination of the character of the hot phase transition in 4d four-fermion NJL-type models is applied to non-supersymmetric and supersymmetric versions o…
Gravitationally Induced Scalar Field Fluctuations in the Radiation Dominated R-W Universe
Zygmunt Lalak, Krzysztof Meissner, Jacek Pawełczyk
It is shown that quantum fluctuations due to a nontrivial gravitational background in the flat radiation dominated universe can play an important cosmological role generating nonva…
