abstract
We present new parametrisations of energy spectra of secondary particles, $\pi$-mesons, gamma-rays, electrons and neutrinos, produced in inelastic proton-proton collisions. The simple analytical approximations based on imulations of proton-proton interactions using the public available SIBYLL code, provide very good accuracy for energy distributions of secondary products in the energy range above 100 GeV. Generally, the recommended analytical formulae deviate from the simulated distributions within a few percent over a large range of $x=E_i/E_p$ - the fraction of energy of the incident proton transferred to the secondaries. Finally, we describe an approximate procedure of continuation of calculations towards low energies, down to the threshold of $\pi$-meson production.

MACSJ0417’s giant radio halo shows spectral steepening and radio–X-ray correlation consistent with turbulence from a 6:1 off-axis merger that preserved the cool core; pure hadronic models are energetically excluded.
Gamma-ray upper limits from five high-energy observatories constrain the annihilation cross sections of composite dark matter in the mass range 10^5--10^12 GeV.
Hadronic proton-proton interactions in a superdiffusive one-zone model with proton luminosity 0.14 of spin-down power and diffusion index 1.05 reproduce the 7-200 TeV gamma-ray spectrum from PSR J0622+3749 halo at ambient density 1 cm^{-3}.
Monte Carlo simulations of nuclear cascades in NGC 1068 demonstrate that injected nuclear composition imprints on neutrino and gamma-ray spectra, supported by a re-analysis of archival COMPTEL observations.
Numerical transport modeling of the Cygnus Bubble finds that spatially dependent Bohm diffusion and strong suppression of the diffusion coefficient over at least 150 pc are required to match the observed gamma-ray spectrum and morphology, implying extreme assumptions for steady hadronic acceleration
Synchrotron self-absorption alters radiation-mediated shock profiles for magnetizations above 10^{-8}, subshocks appear above 0.1, and hadronic processes add a high-energy photon tail with negligible effect on overall shock dynamics.
Alternative ISRF models produce only modest changes to the LHAASO diffuse gamma-ray fit; the associated pp neutrinos remain consistent with IceCube all-sky data and compatible with ANTARES/KM3NeT limits.
Reviews IceCube neutrino results, models Galactic plane flux from cosmic ray interactions with the interstellar medium, and discusses prospects for identifying PeVatrons via LHAASO sources.
