We predict an exotic Z^+ baryon (having spin 1/2, isospin 0 and strangeness +1) with a relatively low mass of about 1530 MeV and total width of less than 15 MeV. It seems that this region of masses has avoided thorough searches in the past.

$S$-wave $KN$ scattering in a renormalizable chiral effective field theory
A renormalizable covariant chiral EFT calculation of s-wave KN scattering yields a good description of I=1 phase shifts with a negative effective range while the I=0 channel remains weakly constrained.

Chiral Structure and Selection Rules in Light-Front Nucleon-Pentaquark Mixing
Symmetry selection rules restrict nucleon-pentaquark mixing to 6 of 27 positive-parity states, with sigma and pi transitions adding incoherently to a total five-quark probability of 29%.
