Exotic decays of the Standard Model-like Higgs boson into beyond-the-Standard Model particles are predicted in a wide range well-motivated theories. The enormous samples bosons that have been and will be produced at Large Hadron Collider thus constitute one key discovery opportunities facility, particularly upcoming high-statistics high-luminosity run. Here we review recent theoretical work on ...

After some brief personal recollections about V.N.Gribov, I demonstrate that his results and ideas on complex angular momenta may be applied in unfamiliar directions. As an example, it is shown, that any strong interaction amplitude, satisfying dispersion relation (in momentum transfer), has infinite number of energy-plane poles, both for exotic and non-exotic quantum numbers. This result ensur...
