Module variables

Traits and structs which can be used to extract complex information from Events.

Structs

Angles

A struct for obtaining both spherical angles at the same time.

CosTheta

A struct for obtaining the $\cos\theta$ (cosine of the polar angle) of a decay product in a given reference frame of its parent resonance.

Mandelstam

A struct used to calculate Mandelstam variables ($s$, $t$, or $u$).

Mass

A struct for obtaining the mass of a particle by indexing the four-momenta of an event, adding together multiple four-momenta if more than one index is given.

Phi

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

PolAngle

A struct defining the polarization angle for a beam relative to the production plane.

PolMagnitude

A struct defining the polarization magnitude for a beam relative to the production plane.

Polarization

A struct for obtaining both the polarization angle and magnitude at the same time.

Enums

VariableExpression

Expressions which can be used to compare Variables to Floats.

Traits

Variable

Standard methods for extracting some value out of an Event.

Functions

not

A method which negates the given expression.
