We found a strong enhancement of the rate of the decay of π0-meson into scalar and pseudoscalar bosons as compared with its decay into two photons. The branching ratio of this mode can be as large as BR(π0→S+P)≃10−6–10−5, which is very interesting from the experimental point of view.

During their acceleration, both UHECR nuclei and UHECR protons may interact with the radiation field present in the accelerator region leading to photo-disintegration and photo-pion production interactions respectively. This leads to a close connection between the degree of disintegration of UHECR nuclei and the UHE neutrino flux produced by a source. Upon escaping the accelerator, UHECR protons go on to generate a secondary UHE photon flux through photo-pion interactions with the cosmic microwave background (CMB) photons, These secondary UHE photons produced (via neutral pion decay) will themselves also interact with the cosmic radio background (CRB) photons. This leads to a second connection between UHE photons and nearby source of UHECR protons. We hear investigate both these connections to draw conclusions on what we can learn about UHECR sources.
