Hi all
i need to know how i can square the amplitude of any decay
by using feyncalc or any program else
note that my formula which i get it from inserting the amplitude
in feyncalc program include some scalar functions
as (B_0, C_0, C_1, C_2, C_11, C_12, ...)
these functions that i can't square them
if any one can help me and tell me the command which i can use
it to solve my problem or any other solution, i will be so happy
and thankful for him or her.
my operatring system is Linux and i use mathematica 6.2 and
feyncalc 6.0
thanks
Hayam
