HadronicLineshapes

The HadronicLineshapes a Julia package provides models for description of hadronic scattering processes within particle physics.

Installation

To install HadronicLineshapes, use the Julia package manager. From the Julia REPL, enter package mode by pressing ], then run:

pkg> add https://github.com/mmikhasenko/HadronicLineshapes.jl

Ensure that you have Julia installed on your system and that the Parameters package, a dependency of HadronicLineshapes, is also installed using the same method.

Usage and API Reference

Basic Usage

using HadronicLineshapes

# Create a Breit-Wigner
bw = BreitWigner(1.6, 0.2) # constant-width lineshape function
bw = BreitWigner(1.6, 0.2, 0.1, 0.2, 1, 1.5) # P-wave
bw = BreitWigner(; m = 1.6, Γ = 0.2, ma = 0.1, mb = 0.2, l = 1, d = 1.5) # same as above
#
mbw = MultichannelBreitWigner(
    1.6,
    [
        (gsq = 0.35, ma = 0.1, mb = 0.2, l = 0, d = 1.0),
        (gsq = 0.35, ma = 0.3, mb = 0.25, l = 0, d = 1.5),
    ],
)
mbw = Flatte(1.6, 0.35, 0.1, 0.2, 0.35, 0.3, 0.25) # same as above

See detailed definition in lineshape documentation

API Overview

All of the lineshapes are inherited from AbstractFlexFunc enabling mathematical operations on the functions like multiplication and composition.

  • AbstractFlexFunc: Base type for flexible function operations.
  • WrapFlexFunction: a simple wrapper for a lambda function.
  • ComposeFlexFunc: a composition of two functions f(g(x)).
  • ScaleFlexFunc: a scaled version of a function f(x) * a.
  • ProductFlexFunc: a product of two functions f(x) * g(x).
