dispersion_relation

<code>double</code>. CM energy in lattice units, \(aE\).

energy

<code>integer</code>. Total momentum squared of the moving frame in lattice units, \(d^2\).

momentum_d

<code>integer</code>. Spatial extent of the lattice as a dimensionless quantity, \(L/a\).

extent_space

plus

Boolean. Use the lattice dispersion relation instead of the continuum one

lattice_disp

Converts a center of mass (CM) frame energy to the lattice frame using the
continuum dispersion relation.

Toolkit to perform statistical analyses of correlation
functions generated from Lattice Monte Carlo simulations. In
particular, a class 'cf' for correlation functions and
methods to analyse those are defined. This includes (blocked)
bootstrap (based on the 'boot' package) and jackknife, but also an
automatic determination of integrated autocorrelation
times. 'hadron' also provides a very general function
bootstrap.nlsfit() to bootstrap a non-linear least squares fit.
More specific functions are provided to extract hadronic quantities
from Lattice Quantum Chromodynamics simulations, a particular Monte
Carlo simulation,(see e.g. European Twisted Mass Collaboration, P. Boucaud et
al. (2008) <doi:10.1016/j.cpc.2008.06.013>). Here, to determine
energy eigenvalues of hadronic states, specific fitting routines
and in particular the generalised eigenvalue method (see
e.g. B. Blossier et al. (2009) <doi:10.1088/1126-6708/2009/04/094>
and M. Fischer et al. (2020)
<https://inspirehep.net/literature/1792113>) are implemented.
In addition, input/output and plotting routines are available.
