Vacuum Cherenkov radiation for nonminimal dimension-5 Lorentz violation
A. Yu. Petrov, M. Schreck, A. R. Vieira
Vacuum Cherenkov radiation is investigated in the Lorentz-violating Standard-Model Extension for isotropic dim-5 operators and in the fermion sector. Both the…

An exact stationary axisymmetric vacuum solution within a metric--affine bumblebee gravity
A. A. Araújo Filho, J. R. Nascimento, A. Yu. Petrov +1
Within the framework of the spontaneous Lorentz symmetry breaking, we consider a metric--affine generalization of the gravitational sector of the Standard--Model Extension (SME), i…

Supersymmetry breaking
Yael Shadmi
These lectures provide a simple introduction to supersymmetry breaking. After presenting the basics of the subject and illustrating them in tree-level examples, we discuss dynamica…
