Struct PyEvent 

pub struct PyEvent {
    pub event: Event,
    /* private fields */
}

A single event

Events are composed of a set of 4-momenta of particles in the overall center-of-momentum frame, optional auxiliary scalars (e.g. polarization magnitude or angle), and a weight.

Parameters

p4s : list of Vec4 4-momenta of each particle in the event in the overall center-of-momentum frame aux: list of float Scalar auxiliary data associated with the event weight : float The weight associated with this event p4_names : list of str, optional Human-readable aliases for each four-momentum. Providing names enables name-based lookups when evaluating variables. aux_names : list of str, optional Aliases for auxiliary scalars corresponding to aux. aliases : dict of {str: str or liststr}, optional Additional particle identifiers that reference one or more entries from p4_names.

Examples

from laddu import Event, Vec3 # doctest: +SKIP event = Event( # doctest: +SKIP … [Vec3(0.0, 0.0, 1.0).with_mass(0.0), Vec3(0.0, 0.0, 1.0).with_mass(0.0)], … [], … 1.0, … p4_names=[‘kshort1’, ‘kshort2’], … aliases={‘pair’: [‘kshort1’, ‘kshort2’]}, … ) event.p4(‘pair’) # doctest: +SKIP Vec4(px=0.0, py=0.0, pz=2.0, e=2.0)

Fields

event: Event

Implementations

impl PyEvent

pub fn boost_to_rest_frame_of(&self, names: Vec<String>) -> PyResult<Self>

Boost all the four-momenta in the event to the rest frame of the given set of four-momenta by indices.

Parameters

names : list of str The names of the four-momenta whose rest frame should be used for the boost

Returns

Event The boosted event

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<PyEvent>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
