Gauge Trimming of Neutrino Masses
Mu-Chun Chen, Andre de Gouvea, Bogdan A. Dobrescu
We show that under a new U(1) gauge symmetry, which is non-anomalous in the presence of one ``right-handed neutrino'' per generation and consistent with the standard model Yukawa c…
Small x Behavior of Parton Distributions from the Observed Froissart Energy Dependence of the Deep Inelastic Scattering Cross Section
M. M. Block, E. L. Berger, C. -I. Tan
We fit the reduced cross section for deep-inelastic electron scattering data to a three parameter ln^2 s fit, A + beta ln^2 (s/s_0), where s= [Q^2/x] (1-x) + m^2, and Q^2 is the vi…
Small Visible Energy Scalar Top Iterative Discriminant Analysis
A. Sopczak, A. Finch, A. Freitas +2
Light scalar top quarks with a small mass difference with respect to the neutralino mass are of particular cosmological interest. This study uses an Iterative Discriminant Analysis…
Hadronic forward scattering: Predictions for the Large Hadron Collider and cosmic rays
Martin M. Block
The status of hadron-hadron interactions is reviewed, with emphasis on the forward and near-forward scattering regions. From analyticity, Finite Energy Sum Rules are introduced fro…
The Elusive p-air Cross Section
Martin M. Block
For the $\pbar p$ and systems, we have used all of the extensive data of the Particle Data Group[K. Hagiwara {\em et al.} (Particle Data Group), Phys. Rev. D 66, 010001 (2002)…
Stop Decay into Right-handed Sneutrino LSP at Hadron Colliders
Andre de Gouvea, Shrihari Gopalakrishna, Werner Porod
Right-handed neutrinos offer us the possibility of accommodating neutrino masses. In a supersymmetric model, this implies the existence of right-handed sneutrinos. Right-handed sne…
