Scalar field dark matter, cross section and Planck-scale physics [PDF]

, 2002
In recent papers we have proposed that the dark matter of the Universe could be from scalar field origin. In this letter, we find that if the scale of renormalization of the model is of order of the Planck Mass, then a scalar field $\Phi $ endowed with ...

New physics, the cosmic ray spectrum knee, and pp cross section measurements [PDF]

, 2010
We explore the possibility that a new physics interaction can provide an explanation for the knee just above $10^6$ GeV in the cosmic ray spectrum. We model the new physics modifications to the total proton-proton cross section with an incoherent term ...

The Search for New Physics by the Measurement of the Four-Jet Cross-Section at LHC and Tevatron [PDF]

, 1997
We investigate the possibility to look for new physics by the measurement of the 4-jet cross section at LHC and FNAL. In particular, we consider the model with scalar colour octet and the supersymmetric model with R-parity violation.

New Predictions for Neutrino Telescope Event Rates [PDF]

, 1996
Recent measurements of the small-$x$ deep-inelastic regime at HERA translate to new expectations for the neutrino-nucleon cross section at ultrahigh energies. We present event rates for large underground neutrino telescopes based on the new cross section

DIPSI: a Monte Carlo generator for elastic vector meson production in charged lepton-proton scattering [PDF]

, 1996
We present a Monte Carlo generator for exclusive vector meson production in charged lepton-proton interactions, l+p --> l+p+V, based on a QCD leading logarithm model calculation according to which the cross section for this process is proportional to the

Jets and threshold summation in Deductor [PDF]

, 2017
We explore jet physics in hadron collisions using the parton shower event generator Deductor. Of particular interest is the one jet inclusive cross section dsigma/dpT for jets of very high pT.

Cross Sections and Lorentz Violation [PDF]

, 2001
The derivation of cross sections and decay rates in the Lorentz-violating standard-model extension is discussed. General features of the physics are described, and some conceptual and calculational issues are addressed.

Constraints on Neutrino-Nucleon Interactions at energies of 1 EeV with the IceCube Neutrino Observatory

, 2010
A search for extremely high energy cosmic neutrinos has been carried out with the IceCube Neutrino Observatory. The main signals in the search are neutrino-induced energetic charged leptons and their rate depends on the neutrino-nucleon cross section ...

Extra Dimensions and Higgs Pair Production at Photon Colliders [PDF]

, 1999
We show that new physics effects due to extra dimensions can dramatically affect Higgs pair production at photon colliders. We find that the cross section due to extra dimensions with the scale $M_S$ of new physics around 1.5 TeV, the cross section can ...

Soft Photoproduction Physics [PDF]

, 1995
Several topics of interest in soft photoproduction physics are discussed. These include jet universality issues (particle flavour composition), the subdivision into event classes, the buildup of the total photoproduction cross section and the effects of ...
