A Search for New Particles Produced by High Energy Photons*
A search for new particle s which might be produced by photons of energy up to 18 GeV is described. No new particles were found. Calculations of the Beth&-Heitler process are described which make it possible to state that this exper.iment would have detected non-strongly interacting particles whose mass and lifetime lay in a definite range, did they exist.
متن کاملSearch for Ultra-high Energy Photons Using Air Showers
The observation of photons with energies above 10 eV would open a new window in cosmic-ray research, with possible impact on astrophysics, particle physics, cosmology and fundamental physics. Current and planned air shower experiments, particularly the Pierre Auger Observatory, offer an unprecedented opportunity to search for such photons and to complement efforts of multi-messenger observation...
متن کاملSearch for Dark Photons Produced in 13 TeV pp Collisions.
Searches are performed for both promptlike and long-lived dark photons, A^{'}, produced in proton-proton collisions at a center-of-mass energy of 13 TeV, using A^{'}→μ^{+}μ^{-} decays and a data sample corresponding to an integrated luminosity of 1.6 fb^{-1} collected with the LHCb detector. The promptlike A^{'} search covers the mass range from near the dimuon threshold up to 70 GeV, while th...
متن کاملSecondary Particles Produced by Hadron Therapy
Introduction Use of hadron therapy as an advanced radiotherapy technique is increasing. In this method, secondary particles are produced through primary beam interactions with the beam-transport system and the patient’s body. In this study, Monte Carlo simulations were employed to determine the dose of produced secondary particles, particularly neutrons during treatment. Materials and Methods I...
متن کاملAxionic Shortcuts for High Energy Photons
We study the photon axion mixing in the presence of large extra dimensions. The eigenvalues and eigenstates of the mixing matrix are analyzed and we establish the resonance condition for the total conversion of a high energy photon into a Kaluza-Klein (KK) axion state. This resonant transition, a photon transformed into a KK axion travelling freely through the bulk and converting back into a ph...
