Struct Acts::Neutral

struct Neutral

Charge and momentum interpretation for neutral particles.

Public Functions

constexpr Neutral() = default

inline constexpr Neutral(float absQ) noexcept

Construct and verify the input charge magnitude (in debug builds).

This constructor is only provided to allow consistent construction.

inline constexpr float absQ() const noexcept

template<typename T>
inline constexpr auto extractCharge(T) const noexcept

template<typename T>
inline constexpr auto extractMomentum(T qOverP) const noexcept

template<typename P, typename Q>
inline constexpr auto qOverP(P momentum, Q signedQ) const noexcept

Friends

inline friend constexpr bool operator==(Neutral, Neutral) noexcept

Compare for equality.

This is always true as Neutral has no internal state. Must be available to provide a consistent interface.
