Query: Analytic results for Sudakov form factors in QCD   Sudakov form factors appear ubiquitously in factorized cross sections where
they allow one to resum large logarithms to all orders in perturbation theory.
Their exact evaluation requires numerical integrals over anomalous dimensions,
which in practice can hamper efficiency. Alternatively, one can use approximate
analytic solutions, which provide fast evaluation at the cost of numerical
precision and loss of properties such as renormalization group invariance. We
provide an exact analytic expression of the QCD Sudakov form factor which
allows one to obtain fast and numerically exact results.
