Detailed Description

Event shape global variable : second Fox-Wolfram moment, H(2)

Created by KVClassFactory on Tue Nov 27 17:47:49 2007 Author: franklan

We use the following formula:

\[ H_{2} = \frac{\sum_{i,j} |p_{i}| |p_{j}| (3cos^{2}\theta_{rel} - 1) }{2\sum_{i,j} |p_{i}||p_{j}|} \]

to calculate $H(2)$. By default, momenta in "CM" frame are used. (change with SetFrame()).
