Some topics of fundamental physics attainable with IACTs

Astrophysical gamma rays in the TeV regime are valid probes of new physics because of the high energies, large distances and/or times involved in the processes. The program of current ground-based imaging atmospheric Cherenkov telescopes (IACTs) on fundamental physics is wide: from the search of particle dark matter annihilation or decays (heavy and light) or other proposed exotic objects such as magnetic monopoles or quark nuggets, to that of signatures of new physics such that coming from Lorentz Invariance violation theories or involving tau neutrinos. This ample and complex program runs for more than a decade now within HESS, MAGIC and VERITAS, the current major IACTs, in strong competition with the astrophysical observation program. In this presentation, I will discuss some of these topics, arguing on the lessons learnt and the things to come for CTA and other future facilities.
