Extreme BL Lacs provide intense and hard beams of very-high energy photons that can be exploited to explore physical processes beyond those foreseen by the present standard model (SM) of particle physics. In particular, the potential extension of the spectrum of extreme BL Lacs well above the ~10 TeV, limit achieved by the current instruments, will provide the opportunity to test effects...

Axion-like particles (ALPs) are very light, neutral, pseudo-scalar bosons predicted by the String Theory and are supposed to interact with two photons. In the presence of an external magnetic field ALPs produce very interesting astrophysical effects in the very-high energy (VHE) band and above (10 GeV – 1000 TeV). ALPs can influence the emission of extreme BL Lacs (EHBLs): in particular,...
