DESCRIPTION:Speakers: Ivan Maslakov (Nikolaevich)\nWe investigate a model 
 with a gauge boson of the baryonic U(1)_B group.\n\nRelevance: Problems of
  dark matter and baryon asymmetry of the Universe\n\nObjectives:\n-Constru
 ction of the Lagrangian for baryon‑photon interactions with hadrons at e
 nergy scales typical of current detectors.\n-Calculation of the baryon‑p
 hoton production cross section in the main channels.\n-Estimation of the p
 arameters of visible decays.\n-Estimation of the sensitivity of current de
 tectors.\n\nMethods:\n-We derive the mixing form factors of the baryon‑p
 hoton with vector mesons from the chiral sigma model.\n-Low‑energy theor
 y (TiMoFey detector): within chiral theory\, we take into account resonanc
 es that contribute at the characteristic energy scale. We calculate the ba
 ryon‑photon production cross section in the main channels (πN and NN co
 llisions).\n-High‑energy theory: to calculate the production cross secti
 on in pp collisions at a higher energy scale\, we use the tensor pomeron e
 xchange notation. \n\nResults:\n-We determine the sensitivity of the TiMoF
 ey detector. \n-Also we consider general vector and axial vector particle 
 (coresponding to arbitrary U(1) group\, but not only baryon). We obtained 
 decay channels and nucleon vertexes for such models.\n\nPlans:\n-The sensi
 tivity of high-energy detectors will be determined in the near future with
  the approach of the interference exchange.\n\nhttps://indico.particle.mep
