Hadronic parity violation is studied in the photo-disintegration of the deuteron at low energies. We calculate the parity-violating spin asymmetries $P_{x'}$ and $P_{z'}$ with the polarized outgoing neutrons. Non-vanishing asymmetry arises from the interference of opposite parity states in the initial and final state wave functions. Parity admixtures are accounted by using a pionless effective...

Many extensions of the standard model contain an additional $U(1)^\prime$ gauge group with an associated $Z^\prime$ gauge boson. In some of those constructions the $U(1)^\prime$ charges are generation dependent and therefore introduce tree-level flavor changing neutral currents mediated by the $Z^\prime$. We discuss the phenomenology of these FCNC couplings for meson decays and possible LHC...

Time reversal invariance violating (TRIV) effects in low energy physics could be very important for a search for new physics, being complementary to neutron and atomic electric dipole moment (EDM) measurements. In this relation, we discuss a sensitivity of some TRIV observables in neutron scattering and nuclear EDMs to different models of time-reversal (CP) violation and their dependencies on...

The phase diagram of QCD at non-zero chemical potential is difficult to calculate from first principles because the coupling strength is large, preventing ordinary perturbation theory, and the action is complex, leading to the "sign problem" and preventing conventional lattice simulations. To understand better how to deal with complex actions and to obtain a qualitative picture of the phase...

Warped extra dimensions (WED) are among the most popular alternatives to supersymmetry for addressing the gauge hierarchy problem. In addition, they simultaneously allow for an elegant explanation of the observed fermion mass hierarchy and hierarchical quark mixing by virtue of wave function overlaps along the extra (spatial) dimension. Strong constraints on models with WED come from...
