Nuclearites—a novel form of cosmic radiation
E. Witten (personal communication) has raised the intriguing possibility that nuclear matter consisting of aggregates of up, down and strange quarks in roughly equal proportions may be less massive
Hadron Masses in a Gauge Theory
We explore the implications for hadron spectroscopy of the "standard" gauge model of weak, electromagnetic, and strong interactions. The model involves four types of fractionally charged quarks, each
Neutrinoless double electron-capture as a tool to measure the electron neutrino mass
A nucleus (Z, A) may capture two atomic electrons to become (Z − 2, A). For Majorana neutrinos this may occur with no neutrino emission, the process is a virtual mixing of the parent atom and the
Charged dark matter
Abstract We propose that dark matter is made of CHAMP's, charged massive particles that survive annihilation in the early Universe. We constrain champs to be matter-antimatter symmetric, to provide
On the optical and X-ray afterglows of gamma ray bursts
We severely criticize the consuetudinary analysis of the afterglows of gamma-ray bursts (GRBs) in the conical-ejection fireball scenarios. We argue that, instead, recent observations imply that the
A Matter-Antimatter Universe?
We ask whether the universe can be a patchwork consisting of distinct regions of matter and antimatter. We demonstrate that, after recombination, it is impossible to avoid annihilation near regional
Calorimetric measurements of 163holmium decay as tools to determine the electron neutrino mass
Abstract We compute the spectrum of “calorimetric” energy in the electron capture decay of 163 Ho. A calorimetric experiment would yield an excellent determination of the ( 163 Ho, 163 Dy) mass
QCD predictions for hadronic final states in e+e− annihilation
Abstract We defend the applicability of asymptotically free QCD perturbation theory to the description of multi-jet hadronic final states and investigate its predictions for the process e + e − →
Neutrino oscillation physics with a neutrino factory
Abstract Data from atmospheric and solar neutrinos indicate that there are at least three neutrino types involved in oscillation phenomena. Even if the corresponding neutrino mass scales are very
Measuring the W-Boson mass at a hadron collider: a study of phase-space singularity methods
The traditional method to measure the W Boson mass at a hadron collider (more precisely, its ratio to the Z boson mass) utilizes the distributions of three variables in events where the W decays into
