Noncommutative two-tori with real multiplication as noncommutative projective varieties

Alexander Polishchuk

We define analogues of homogeneous coordinate algebras for noncommutative two-tori with real multiplication. We prove that the categories of standard holomorphic vector bundles on…

Indications of Neutrino Oscillation in a 250 km Long-baseline Experiment

K2K Collaboration, M. H. Ahn

The K2K experiment observes indications of neutrino oscillation: a reduction of flux together with a distortion of the energy spectrum. Fifty-six beam neutrino events are obs…

Bifurcations and Patterns in Compromise Processes

E. Ben-Naim, P. L. Krapivsky, S. Redner

We study an opinion dynamics model in which agents reach compromise via pairwise interactions. When the opinions of two agents are sufficiently close, they both acquire the average…

B_K from quenched overlap QCD

N. Garron, L. Giusti, C. Hoelbling +2

We present an exploratory calculation of the standard model Delta S=2 matrix element relevant for indirect CP violation in K -> pi pi decays. The computation is performed with over…

KamLAND and solar neutrino data eliminate the LOW solution

V. Barger, D. Marfatia

The KamLAND reactor antineutrino experiment has detected a 3.4σflux suppression relative to the expectation if no neutrino oscillations occur. We combine KamLAND data with solar ne…

Adiabatic charge and spin transport in interacting quantum wires

Prashant Sharma, Claudio Chamon

We study charge and spin transport through an interacting quantum wire, caused by backscattering off an effective impurity potential with a periodic time-dependence. The adiabatic…

Hagedorn transition for strings on pp-waves and tori with chemical potentials

Richard C. Brower, David A. Lowe, Chung-I Tan

It has been conjectured that string theory in a pp-wave background is dual to a sector of N=4 supersymmetric Yang-Mills theory. We study the Hagedorn transition for free strings in…

Where is the Higgs boson?

A. Aranda, C. Balazs, J. L. Diaz-Cruz

Electroweak precision measurements indicate that the standard model Higgs boson is light and that it could have already been discovered at LEP 2, or might be found at the Tevatron…

Search for anti-electron-neutrinos from the Sun at Super-Kamiokande-I

Kamiokande collaboration, Y. Gando

We present the results of a search for low energy from the Sun using 1496 days of data from Super-Kamiokande-I. We observe no significant excess of events and set an uppe…

A possible mechanism for cold denaturation of proteins at high pressure

Manuel I. Marques, Jose M. Borreguero, H. Eugene Stanley +1

We study cold denaturation of proteins at high pressures. Using multicanonical Monte Carlo simulations of a model protein in a water bath, we investigate the effect of water densit…

Soliton Ratchets Induced by Excitation of Internal Modes

C. R. Willis, M. Farzaneh

Recently Flach et.al. used a symmetry analysis to predict the appearance of directed energy current in homogeneously spatially extended systems coupled to a heat bath in the presen…

New mathematical structures in renormalizable quantum field theories

Dirk Kreimer

Computations in renormalizable perturbative quantum field theories reveal mathematical structures which go way beyond the formal structure which is usually taken as underlying quan…

Calculation of Nucleon Electromagnetic Form Factors

LHPC, SESAM Collaborations, : +8

The fomalism is developed to express nucleon matrix elements of the electromagnetic current in terms of form factors consistent with the translational, rotational, and parity symme…

Recent Results from the K2K Experiment

C. W. Walter

The K2K experiment has collected approximately half of its allocated protons on target between June of 1999 and July of 2001. These proceedings give a short introduction to the exp…

Spatially heterogeneous ages in glassy dynamics

Horacio E. Castillo, Claudio Chamon, Leticia F. Cugliandolo +2

We construct a framework for the study of fluctuations in the nonequilibrium relaxation of glassy systems with and without quenched disorder. We study two types of two-time local c…

Categories of holomorphic vector bundles on noncommutative two-tori

Alexander Polishchuk, Albert Schwarz

In this paper we study the category of standard holomorphic vector bundles on a noncommutative two-torus. We construct a functor from the derived category of such bundles to the de…

The Top Quark: Experimental Roots and Branches of Theory

E. H. Simmons

The CDF and D0 experiments at the Fermilab Tevatron have discovered the top quark and provided first measurements of many of its properties. The small top sample gathered by Run I…

Models of Flavor with Discrete Symmetries

Alfredo Aranda

In an attempt to understand the observed patterns of lepton and quark masses, models invoking a flavor symmetry , under which the Standard Model generations are charged, have…

How two neutrino superbeam experiments do better than one

V. Barger, D. Marfatia, K. Whisnant

We examine the use of two superbeam neutrino oscillation experiments with baselines $\lsim 1000$ km to resolve parameter degeneracies inherent in the three-neutrino analysis of suc…
