Description
Finite-volume spectrum of the isosinglet strange channel. The attached hdf5 file contains the bootstrap samples for the finite volume spectrum levels used for the Lüscher quantization condition fit. The bootstrap samples are organized in the following group structure,
/PSQ{d^2}/{irrep}/free_levels/
/PSQ{d^2}/{irrep}/e{frame}_{level}/
/PSQ{d^2}/{irrep}/e{frame}_{level}_ref/
/single_hadrons/{hadron}({d^2})/
/single_hadrons/{hadron}({d^2})_ref/
/single_hadrons/ref/
where {d^2} is related to the total momentum squared by P^2=(2π/L)^2 * d^2 where L is the spacial lattice extent, {irrep} indicates the irreducible representation of the relevant little group, {frame} indicates the frame of the energy determination and can be "cm" for center of mass frame or "lab" for lab frame, {level} indicates the energy level of the spectrum, {hadron} indicates a single hadron particle energy and can be "N", "L", "S", "X", "pi", or "k". Further details about each group and single hadron name meanings are explained below. All datasets contain the mean followed by 800 samples in an array.
Single hadron names are defined as:
name used in data file | full single hadron name |
N | nucleon (baryon) |
L | lambda (baryon) |
S | sigma (baryon) |
X | xi (baryon) |
pi | pion (meson) |
k | kaon (meson) |
Further details about each dataset/attribute:
/PSQ{d^2}/{irrep}/free_levels/
- (ATTRIBUTE) Contains a list of the single hadrons used for each levels' ratio fit within the group's irrep.
/PSQ{d^2}/{irrep}/e{frame}_{level}/
- (DATASET) Contains the bootstrap samples for the level within the irrep in lattice units.
/PSQ{d^2}/{irrep}/e{frame}_{level}_ref/
- (DATASET) Contains the bootstrap samples for the level within the irrep in pion mass units.
/single_hadrons/{hadron}({d^2})/
- (DATASET) Contains the bootstrap samples for the single hadron mass in lattice units.
/single_hadrons/{hadron}({d^2})_ref/
- (DATASET) Contains the bootstrap samples for the single hadron mass in pion mass units.
/single_hadrons/ref/
- (DATASET) Pion mass in lattice units. Equivalent to /single_hadrons/pi(0)/
