In hadron: Analysis Framework for Monte Carlo Simulation Data in Physics

Accessor function for gm

Description

Retrieve the entries of the gm list of three-index arrays containing various gamma structures in a natural indexing.

Usage

gm_mu(mu, basis = "chiral_tmlqcd")

Arguments

mu	Number or string denoting Lorentz index (0,1,2,3,4) for γ^μ 5 for γ^5 "Pp" or "Pm" for the positive and negative parity projectors respectively
basis	String, gamma basis to use. Possible values 'ukqcd': UKQCD gamma basis with γ^i, i \in [1,2,3,4] and γ^5 = γ^1 γ^2 γ^3 γ^4, such that 1 = x, 4 = t. 'chiral_tmlqcd': Chiral gamma basis used by tmLQCD with γ^μ, μ \in [0,1,2,3] and γ^5 = γ^0 γ^1 γ^2 γ^3, such that 0 = t, 3 = z.

Value

Returns the requested gamma matrix as a 4x4 complex valued array, see gm.
