Struct FrameAxes 

pub struct FrameAxes { /* private fields */ }

Orthonormal axes used to project decay momenta into an angular-analysis frame.

Implementations

impl FrameAxes

pub fn new(x: Vec3, y: Vec3, z: Vec3) -> LadduResult<Self>

Construct normalized right-handed axes after validating orthogonality.

pub fn from_z_and_plane_normal(z: Vec3, plane_normal: Vec3) -> LadduResult<Self>

Construct right-handed axes from a z axis and a plane normal.

pub fn from_decay_frame( frame: Frame, reference: Vec4, parent: Vec4, spectator: Vec4, system_boost: Vec3, ) -> LadduResult<Self>

Construct decay-frame axes for a reaction root from caller-selected production momenta.

reference, parent, and spectator are lab-frame four-momenta. system_boost is the boost into the frame where the production plane is defined. This keeps named event topology handling outside the frame helper while still sharing the convention-sensitive geometry.

pub fn for_daughter(self, daughter_momentum: Vec3) -> LadduResult<Self>

Construct daughter axes in the current rest frame.

The daughter direction defines the new z axis. The current z axis and daughter direction define the rotation plane, which makes this helper reusable with any parent-axis convention.

pub const fn x(self) -> Vec3

Return the unit x axis.

pub const fn y(self) -> Vec3

Return the unit y axis.

pub const fn z(self) -> Vec3

Return the unit z axis.

pub fn components(self, vector: Vec3) -> Vec3

Project a vector onto these frame axes.

pub fn angles(self, vector: Vec3) -> LadduResult<DecayAngles>

Compute spherical decay angles for a vector expressed in the same rest frame as the axes.

Trait Implementations

impl Clone for FrameAxes

fn clone(&self) -> FrameAxes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FrameAxes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FrameAxes

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FrameAxes

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for FrameAxes

fn eq(&self, other: &FrameAxes) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for FrameAxes

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
