Particle Phenomenology
Quantum Chromodynamics (QCD) in non-integer d = 4 − 2e space-time dimensions possesses a nontrivial critical point where the theory enjoys exact scale and conformal invariance. As consequence there are three symmetry generators that commute with the renormalization group equation for composite operators.
The resulting constraints allow to reconstruct full evolution kernels in physical...

Particle Phenomenology
In the Wilson formulation, lattice gauge theories with compact gauge
group are confining, at least in the strong coupling limit. In addition, the ground state usually preserves discrete symmetries such as translational and charge conjugation symmetry. In this talk, we consider generalized lattice gauge theories: quantum link models and self-adjoint extensions of Wilson-type theories in...

We present the evaluation of the two-loop ${\cal O}(m_e^2/s)$ contribution to the wide-angle high-energy electron-positron scattering in the double-logarithmic approximation.
The origin and the general structure of the power-suppressed
double logarithmic corrections are discussed.

A light stop with mass almost degenerate with the lightest neutralino has important implications on naturalness and dark matter relic abundance, and is hard to search at colliders. In this paper, we study the potential of searching for such stop particles at the LHC from sbottom decays, focusing on two channels with final states 2l+met and 1b1l+met. We found that, if the lightest sbottom...
