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.<br> 0 &lt;mean&gt; #the energy evaluated on the mean<br> 0 &lt;bsample 1&gt; #first boostrap sample<br> ....<br> 0 &lt;bsample 800&gt; #800th boostrap sample The directory structure and file names are as follows. single_hadrons/m_&lt;hadron&gt;_smpls.dat where &lt;hadron&gt; = 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&lt;mom&gt;_&lt;irrep&gt;" and contains files level_&lt;n&gt;_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. <br>
