Acts::BetheHeitlerApproxSingleCmp Struct Reference

#include <acts/blob/sPHENIX/Core/include/Acts/TrackFitting/BetheHeitlerApprox.hpp>

Public Member Functions
constexpr auto	numComponents () const
	Returns the number of components the returned mixture will have.
constexpr bool	validXOverX0 (ActsScalar x) const

Static Public Member Functions
static auto	mixture (const ActsScalar x)

Detailed Description

This class approximates the Bethe-Heitler with only one component. This is mainly inside AtlasBetheHeitlerApprox, but can also be used as the only component approximation (then probably for debugging)

constexpr bool Acts::BetheHeitlerApproxSingleCmp::validXOverX0 ( ActsScalar  x ) const

inline

Checks if an input is valid for the parameterization. The threshold for x/x0 is 0.002 and orientates on the values used in ATLAS
