Detailed Description

template<class OPTS = ExponentialRegulatorOpts>
struct DiFfRG::ExponentialRegulator< OPTS >

Implements one of the standard exponential regulators, i.e.

\[ R_B(k^2,q^2) = k^2 \exp(-(q^2/k^2)^b) \]

Provides the following functions:

  • RB(k2, q2) = \( p^2 r_B(k^2,p^2) \)
  • dq2RB(k2, q2) = \( \frac{\partial}{\partial q^2} R_B(k^2,p^2) \)
  • RBdot(k2, q2) = \( \partial_t R_B(k^2,p^2) \)
  • RF(k2, q2) = \( p r_F(k^2,p^2) \)
  • dq2RF(k2, q2) = \( \frac{\partial}{\partial q^2} R_F(k^2,p^2) \)
  • RFdot(k2, q2) = \( p \partial_ t R_F(k^2,p^2) \)
Template Parameters
bThe exponent in the regulator.
