Opiate dependence in laboratory animals is commonly induced by two methods: (1) subcutaneous (s.c.) insertion of morphine pellets, and (2) daily injections of increasing doses of opiates. While both of these methods reliably induce opiate dependence, they do not allow one to discontinue, and subsequently reestablish steady state opiate plasma levels with(More)
Leading charm hadrons produced in hadron-nucleus interactions cannot be adequately described within the parton fusion model. Recent results on charm baryon production in Σ − A interactions at 330 GeV with the WA89 detector disagree with fusion predictions. Intrinsic heavy quark pairs in the Σ − (dds) wavefunction provide a simple mechanism for producing(More)
What would be the properties of a universe with only one spatial dimension and one time dimension? General relativity in 1+1 dimensions is unique since the two curvature terms in the Einstein field equations cancel. This makes the Einstein field equations algebraic rather than differential equations. This special feature can make 1+1 dimensionality(More)
Data from the first physics run at the Relativistic Heavy-Ion Collider at Brookhaven National Laboratory, Au+Au collisions at sqrt[s(NN)]=130 GeV, have been analyzed by the STAR Collaboration using three-pion correlations with charged pions to study whether pions are emitted independently at freeze-out. We have made a high-statistics measurement of the(More)
This senior project will provide the reader with a brief background about neutrinos, neutrino-less double beta decay, and the CUORE experiment being constructed in the Gran Sasso National Laboratory in Assergi, Italy. The remainder of the paper will follow my experience working as an undergraduate researcher at the laboratory during the summer of 2012. It(More)
Third generation LIGO detectors will be limited by thermal noise at a low frequency band where gravitational wave signals are expected to exist. A large contribution to thermal noise is caused by internal friction of the mirror and suspension elements. In order to meet the quantum mechanical sensitivity limits of the detector, it will be necessary to(More)
Two-particle interferometry, a second-order interference effect, is explored as another possible tool to distinguish between massive Dirac and Majorana neutrinos. A simple theoretical framework is discussed in the context of several gedanken experiments. The method can in principle provide both the mass scale and the quantum nature of the neutrino for a(More)
