A fundamental problem of cosmic ray (CR) physics is the determination of the average properties of Galactic CRs outside the Solar system. Starting from COS-B data in the 1980's, gamma-ray observations of molecular clouds in the Gould Belt above the Galactic plane have been used to deduce the Galactic CR energy spectrum. We reconsider this problem in view of the improved precision of observational data which in turn require a more precise treatment of photon production in proton-proton scatterings. We show that the spectral shape $dN/dp\propto p^{-2.85}$ of CR protons as determined by the PAMELA collaboration in the energy range 80 GeV

“…Using different particle ratios (like K/π or φ/K * ) measured in elementary collisions, values ranging from 0.1 to 0.4 [1,2,[43][44][45] were previously obtained for the strange quark suppression factor λ s = 2ss/(uū + dd), which represents the probability to produce strange quark pairs relative to light quarks [42]. In pp reactions, particle abundances have been successfully described by statistical-thermal models.…”

The production of K * (892) 0 and φ(1020) in pp collisions at √ s = 7 TeV was measured by the AL-ICE experiment at the LHC. The yields and the transverse momentum spectra d 2 N/dydp T at midrapidity |y| < 0.5 in the range 0 < p T < 6 GeV/c for K * (892) 0 and 0.4 < p T < 6 GeV/c for φ(1020) are reported and compared to model predictions. Using the yield of pions, kaons, and baryons measured previously by ALICE at √ s = 7 TeV, the ratiosThe values of the K * /K − , φ/K * and φ/K − ratios are similar to those found at lower centre-of-mass energies. In contrast, the φ/π − ratio, which has been observed to increase with energy, seems to saturate above 200 GeV. The ( + )/φ ratio in the p T range 1-5 GeV/c is found to be in good agreement with the prediction of the HIJING/BB v2.0 model with a strong colour field.

“…Typically, the mesons contributing dominantly to the signal are the pseudo-scalars M = π 0 , η, η , which have a large cross section into photons. For example, the differential meson production cross section in proton-nucleon collisions have been measured in [101,102] at 70 and 400 GeV, respectively. The cross section is normalized to the total inclusive cross section σ(P P → X), which itself depends on the center-of-mass energy.…”

We explore constraints on gauge bosons of a weakly coupled U(1) B−L , U(1) Lµ−Le , U(1) Le−Lτ and U(1) Lµ−Lτ . To do so we apply the full constraining power of experimental bounds derived for a hidden photon of a secluded U(1) X and translate them to the considered gauge groups. In contrast to the secluded hidden photon that acquires universal couplings to charged Standard Model particles through kinetic mixing with the photon, for these gauge groups the couplings to the different Standard Model particles can vary widely. We take finite, computable loop-induced kinetic mixing effects into account, which provide additional sensitivity in a range of experiments. In addition, we collect and extend limits from neutrino experiments as well as astrophysical and cosmological observations and include new constraints from white dwarf cooling. We discuss the reach of future experiments in searching for these gauge bosons.
