-dependence of backward pion multiplicity in neutrino-nucleus interactions

O. Benhar, S. Fantoni, G. I. Lykasov +1

The production of pions emitted backward in inelastic neutrino-nucleus interactions is analyzed within the impulse approximation in the framework of the dual parton model. We focus…

Reformulating the Map Color Theorem

Louis H. Kauffman

This paper discusses reformulations of the problem of coloring plane maps with four colors. The context is the edge-coloring with three colors of cubic graphs such that three disti…

On Filamentations and Virtual Knots

David Hrencecin, Louis H. Kauffman

In this paper, we discuss filamentations on oriented chord diagrams. When a filamentation cannot be realized on an oriented chord diagram, then the corresponding flat virtual knot…

Linear Superposition in Nonlinear Equations

Avinash Khare, Uday Sukhatme

Even though the KdV and modified KdV equations are nonlinear, we show that suitable linear combinations of known periodic solutions involving Jacobi elliptic functions yield a larg…

Search for R-parity Violating Supersymmetry in Dimuon and Four-Jets Channel

D0 collaboration, V. M. Abazov etal

We present results of a search for R-parity-violating decay of the neutralino chi_1^0, taken to be the Lightest Supersymmetric Particle. It is assumed that this decay proceeds thro…

Growth of Betti Numbers

Bryan Clair, Kevin Whyte

Suppose X is any finite complex with vanishing L^2 Betti number. We prove upper bounds on the Betti numbers for regular coverings of X, sublinear in the order of covering. The boun…

Pion Propagation near the QCD Chiral Phase Transition

D. T. Son, M. A. Stephanov

We point out that, in analogy with spin waves in antiferromagnets, all parameters describing the real-time propagation of soft pions at temperatures below the QCD chiral phase tran…

Squark Mixing Contributions to CP violating phase gamma

Darwin Chang, We-Fu Chang, Wai-Yee Keung +2

We investigate the possibility that the CP violation due to the soft supersymmetry breaking terms in squark mixing can give significant contributions to the various related par…

Thermal fluctuations in the interacting pion gas

M. Stephanov

We derive the two-particle fluctuation correlator in a thermal gas of pi-mesons to the lowest order in an interaction due to a resonance exchange. A diagrammatic technique is used.…

Kaon Condensation and Goldstone's Theorem

T. Schaefer, D. T. Son, M. A. Stephanov +2

We consider QCD at a nonzero chemical potential for strangeness. At a critical value of the chemical potential equal to the kaon mass, kaon condensation occurs through a continuous…
