gm: List of arrays of gamma structures

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

List of arrays of gamma structures

Description

List of arrays of 4x4 complex gamma matrices in the tmLQCD chiral gamma basis, where γ^5 = γ^0 γ^1 γ^2 γ^3 = diag(c(1,1,-1,-1)) and the UKQCD gamma basis, where γ^5 = γ^0 γ^1 γ^2 γ^3.

The index mappings are as follows

• gm[['chiral_tmlqcd']][1,,] γ^0

• gm[['chiral_tmlqcd']][2,,] γ^1

• gm[['chiral_tmlqcd']][3,,] γ^2

• gm[['chiral_tmlqcd']][4,,] γ^3

• gm[['chiral_tmlqcd']][5,,] γ^5

• gm[['chiral_tmlqcd']][6,,] positive parity projector \frac{1}{2} (1 + γ^0)

• gm[['chiral_tmlqcd']][7,,] negative parity projector \frac{1}{2} (1 - γ^0)

• gm[['ukqcd']][1,,] γ^1

• gm[['ukqcd']][2,,] γ^2

• gm[['ukqcd']][3,,] γ^3

• gm[['ukqcd']][4,,] γ^4

• gm[['ukqcd']][5,,] γ^5

• gm[['ukqcd']][6,,] positive parity projector \frac{1}{2} (1 + γ^4)

• gm[['ukqcd']][7,,] negative parity projector \frac{1}{2} (1 - γ^4)

The function gm_mu can be used to access its elements using a more "natural" indexing.
