Elastic nucleon-pion scattering at $m_{\pi} = 200~{\rm MeV}$ from lattice QCD

This archive contains bootstrap samples of single-hadron masses and finite-volume nucleon-pion energies used in https://arxiv.org/pdf/2208.03867. Each (ASCII) file contains 802 lines in the following format: 

801 1 0 0 1  #Header line.
0   #the energy evaluated on the mean
0 #first boostrap sample

0 #800th boostrap sample 

The directory structure and file names are as follows. 

single_hadrons/m__smpls.dat  

where = pion or nucleon, contains the single-hadron masses. The I=1/2 and I=3/2 spectra are located in the directories 'isodoublet_nonstrange' and 'isoquartet_nonstrange_fermionic', respectively. Each subdirectory contains a single irrep and is denoted "dsq_" and contains files 

level__ecm_over_m_smpls.dat

for each level. The energies given in these files are normailzed by mpi and are in the center-of-momentum frame.
