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.

  1. $S$-wave $KN$ scattering in a renormalizable chiral effective field theory

    nucl-th 2025-12 unverdicted novelty 6.0 of 10

    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.

  2. Pentaquarks made of light quarks and their admixture to baryons

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Light pentaquark wavefunctions are constructed from permutation symmetry, and a nucleon-pentaquark mixing model yields a five-quark Fock probability P5q of order 0.4.

  3. Generalized Collective Coordinate Quantization of Solitons with Topological Terms

    hep-th 2025-05 conditional novelty 6.0 of 10

    A generalized collective coordinate quantization with a three-way zero mode classification removes the theta+ pentaquark from the SU(3) Skyrme model spectrum, leaving only the nucleon octet and Delta decuplet.

  4. Comprehensive Mass Predictions: From Triply Heavy Baryons to Pentaquarks

    hep-ph 2026-03 unverdicted novelty 4.0 of 10

    Machine learning models trained on known hadron data and an extended Gürsey-Radicati mass formula predict masses for triply heavy baryons and numerous pentaquark states, agreeing with available data and forecasting un...
