Using improved operator product expansion in Borel–Laplace sum rules with ALEPH τ decay data, and determination of pQCD coupling

Using improved operator product expansion in Borel–Laplace sum rules with ALEPH τ decay data, and determination of pQCD coupling

We use improved truncated operator product expansion (OPE) for the Adler function, involving two types of terms with dimension D= 6 , in the double-pinched Borel–Laplace sum rules and finite energy sum rules for the V + A channel strangeless semihadronic τ decays. The generation of the higher order...
