I’d like to use the PaVeReduce function within FeynCalc in Mathematica
to reduce a triangle integral down to bubbles and tadpoles. I found
the
wolfram help page about this function but I did not find what all the
options
meant with the result that I was unable to produce the reduction I
wanted.
I have used other software for this reduction and I know what the answer
is
so I’m just playing about with FeynCalc at the moment. I tried
PaVeReduce[C0[0, m^2, m^2/y, 0, 0, m^2]] // TraditionalForm
but this didn’t do the required reduction. I played about with the options too in
SetOptions[PaVeReduce, A0ToB0 -> True, BReduce -> True, Collecting -> True, Dimension -> True, FCVerbose -> False, Factoring -> Factor2, IsolateNames -> False, Mandelstam -> {}, PaVeAutoReduce -> True, PaVeOrderList -> {}, WriteOutPaVe -> True]
but couldn’t get the reduction to go ahead.
Thanks for any comments! There is also the possibility that I am using
the wrong
function because I know that Pass-Velt prescription is usually done for
the reduction
of tensor to scalar integrals and I’m trying to do a scalar to sum of
simpler scalar
integrals reduction.
