Invisible decays of ultra-high energy neutrinos

*Correspondence: Omar G. Miranda, Departamento de Física, Centro de Investigación y de Estudios Avanzados del IPN, Av. IPN 2508, Apdo. Postal 14-740, México, DF, Mexico e-mail: [email protected] Gamma-ray bursts (GRBs) are expected to provide a source of ultra high energy cosmic rays, accompanied with potentially detectable neutrinos at neutrino telescopes. Recently, IceCube has set an upper...

Nuclear like effects in proton-proton collisions at high energy

We show that several effects considered nuclear effects are not nuclear in the sense that they do not only occur in nucleus-nucleus and hadron-nucleus collisions but, as well, they are present in hadron-hadron (proton-proton) collisions. The matter creation mechanism in hh, hA and AA collision is always the same. The pT suppression of particles produced in large multiplicity events compared to ...

High-energy proton imaging for biomedical applications

The charged particle community is looking for techniques exploiting proton interactions instead of X-ray absorption for creating images of human tissue. Due to multiple Coulomb scattering inside the measured object it has shown to be highly non-trivial to achieve sufficient spatial resolution. We present imaging of biological tissue with a proton microscope. This device relies on magnetic optic...

Proton and Ion Radiography for High Energy Density Physics Experiments

High Energy Density (HED) experiments at the HHT experimental site of the GSI Plasma Physics Group employ intense, energetic uranium beams in order to study new regimes of the equation of state (EOS) of matter under extreme conditions. A key parameter to be determined in these experiments is the density distribution in the irradiated and heated target. Determining the spatial and density distri...
