Detailed Description

template<typename T>
class HLTAlphaTFilter< T >

Author: Bryn Mathias Adam Elwood; Bryn Mathias Mark Baber, Adam Elwood

Filter for the AlphaT SUSY analysis Makes a trigger decision based on the event HT and the AlphaT value. AlphaT cut is chosen to reject all the QCD background
