Uncontract

Description

Uncontract[exp, q1, q2, ...] uncontracts Eps and DiracGamma. Uncontract[exp, q1, q2, Pair -> {p}] uncontracts also p.q1 and p.q2; the option Pair -> All uncontracts all momenta except OPEDelta.

By default scalar products are not uncontracted.

With the option Pair->All they are “uncontracted ”.
