Struct Phi

pub struct Phi { /* private fields */ }

A struct for obtaining the $\phi$ angle (azimuthal angle) of a decay product in a given reference frame of its parent resonance.

Implementations

impl Phi

pub fn new<T: AsRef<[usize]>, U: AsRef<[usize]>, V: AsRef<[usize]>>( beam: usize, recoil: T, daughter: U, resonance: V, frame: Frame, ) -> Self

Construct the angle given the four-momentum indices for each specified particle. Fields which can take lists of more than one index will add the relevant four-momenta to make a new particle from the constituents. See Frame for options regarding the reference frame.

Trait Implementations

impl Clone for Phi

fn clone(&self) -> Phi

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Phi

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

Formats the value using the given formatter.

impl Default for Phi

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Phi

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Phi

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

Formats the value using the given formatter.

impl Serialize for Phi

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Variable for Phi

fn value(&self, event: &Event) -> Float

This method takes an Event and extracts a single value (like the mass of a particle).

fn value_on_local(&self, dataset: &Arc<Dataset>) -> Vec<Float>

This method distributes the Variable::value method over each Event in a Dataset (non-MPI version).

fn value_on(&self, dataset: &Arc<Dataset>) -> Vec<Float>

This method distributes the Variable::value method over each Event in a Dataset.
