◆ betaBisection()

Herwig::betaBisection::betaBisection ( CrossSection  soft,
DiffXSec  dsig,
Energy  ptmin 
)
inline

Constructor.

Parameters
soft= soft cross section, i.e. the integral of the soft pt spectrum f(u=p_T^2) = dsig exp(-beta*u/u_min)
dsig= dsigma_hard/dp_T^2 at the p_T cutoff
ptmin= p_T cutoff
