Scientific paper

We take the time constraints obtained from recent observations of rapid TeV variability of minute-scale flares in TeV Blazars, and combine them with the time-scale estimates of different particle acceleration mechanisms. We compare the processes and estimate their suitability in producing sufficiently high-energy particles in short enough time to have significance in being able to (i) energise particles to produce rapid flaring, (ii) account for gradual acceleration that could explain the energy-dependent time delays in a recent gamma-ray flare of Markarian 501. We are able to exclude the neutron-based converter mechanism and the shear acceleration as the main processes for energisation of the radiating particles, and suggest the stochastic acceleration as a promising candidate for the time delay in Mkn 501.
