Cosmic Ray "Knee": A Herald of New Physics?
D. Kazanas, A. Nicolaidis
We propose that the knee in the cosmic ray spectrum at energies E ~ 10^{15.5} eV is due to "new physics", namely to a channel in the high energy (~ TeV in the CM) proton interactio…

TeV Neutrinos in a dense medium
A. Nicolaidis, G. Tsirigoti, J. Hansson
The dispersion relation of energetic (few TeV) neutrinos traversing a medium is studied. We use the real time formalism of thermal field theory and we include the effects from the…

Is Dark Matter made up of Massive Quark Objects?
S. Fredriksson, D. Enstrom, J. Hansson +2
We suggest that dark matter is made up of massive quark objects that have survived from the Big Bang, representing the ground state of ``baryonic'' matter. Hence, there was no over…
