QCD Loop Corrections to Top Production and Decay at e^+ e^- Colliders
Cosmin Macesanu
We present a computation of QCD next-to-leading order virtual corrections to the top production and decay process at linear colliders. The top quarks are allowed to be off-shell an…
Entropy of Operator-valued Random Variables: A Variational Principle for Large N Matrix Models
L. Akant, G. S. Krishnaswami, S. G. Rajeev
We show that, in 't Hooft's large N limit, matrix models can be formulated as a classical theory whose equations of motion are the factorized Schwinger--Dyson equations. We discove…
Quantum fast Fourier transform using multilevel atoms
Ashok Muthukrishnan, C. R. Stroud
We propose an implementation of the quantum fast Fourier transform algorithm in an entangled system of multilevel atoms. The Fourier transform occurs naturally in the unitary time…
Kronecker delta energy terms in thermal field theory
F. T. Brandt, Ashok Das, J. Frenkel +1
We discuss, using the imaginary time method, some aspects of the connection between the Ward identity, the non-analyticity of amplitudes and the causality relation in QED at finite…
The Calderon problem for conormal potentials, I: Global uniqueness and reconstruction
Allan Greenleaf, Matti Lassas, Gunther Uhlmann
In dimensions greater than or equal to three, we establish global uniqueness and obtain reconstruction in the Calderon problem for the Schrodinger equation with certain singular po…
Observation of Exclusive barB --> D(*) K*- Decays
R. Mahapatra, CLEO Collaboration
We report the first observation of the exclusive decays \bar B\to D^{(*)}K^{*-}, using 9.66 x 10^{6} B\bar{B} pairs collected at the Υ(4S) with the CLEO detector. We measure the fo…
Systematics of Charged Particle Production in Heavy-Ion Collisions with the PHOBOS Detector at RHIC
Peter A. Steinberg
The multiplicity of charged particles produced in Au+Au collisions as a function of energy, centrality, rapidity and azimuthal angle has been measured with the PHOBOS detector at R…
Search for CP Violation in τ-> Kπν_τDecays
G. Bonvicini, CLEO Collaboration
We search and find no evidence for CP violation in tau decays into the K pi nu final state. We provide confidence limits on the imaginary part of the coupling constant Lambda, desc…
Measurement of the Total Cross Section and Differential Cross Section in Collisions at TeV
The CDF collaboration
We present measurements of the B+ meson total cross section and differential cross section . The measurements use a pb^{-1} sample of collisions at $…
Non-Abelian Thermal Large Gauge Transformations in 2+1 Dimensions
F. T. Brandt, Ashok Das, Gerald V. Dunne +2
We discuss several different constructions of non-Abelian large gauge transformations at finite temperature. Pisarski's ansatz with even winding number is related to Hopf mappings,…
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…
Search for Leptoquark Pairs Decaying to neutrino neutrino + jets in p anti-p Collisions at s**(1/2)=1.8 TeV
D0 Collaboration, V. M. Abazov
We present the results of a search for leptoquark (LQ) pairs in (85.2 +- 3.7) pb^{-1} of p anti-p collider data collected by the D0 experiment at the Fermilab Tevatron. We observe…
Measurement of the Xi^+_c Lifetime
CLEO Collaboration, A. H. Mahmood
The Xi^+_c lifetime is measured using 9.0 fb^-1 of e+e- annihilation data collected on and just below the Upsilon(4S) resonance with the CLEO II.V detector at CESR. This is the fir…
Entanglement of internal and external angular momenta of a single atom
Ashok Muthukrishnan, C. R. Stroud
We consider the exchange of spin and orbital angular momenta between a circularly polarized Laguerre-Gaussian beam of light and a single atom trapped in a two-dimensional harmonic…
Lifetime Differences, direct CP Violation and Partial Widths in D0 Meson Decays to K+K- and pi+pi-
S. E. Csorna, CLEO Collaboration
We describe several measurements using the decays D0->K+K- and pi+pi-. We find the ratio of partial widths, Gamma(D0->K+K-)/Gamma(D0->pi+pi-), to be 2.96+/-0.16+/-0.15, where the f…
High resolution Chandra HETG and RXTE observations of GRS 1915+105 : A hot disk atmosphere & cold gas enriched in Iron and Silicon
J. C. Lee, C. S. Reynolds, N. S. Schulz +3
The time-averaged 30 ks Chandra HETGS observation of the micro-quasar GRS 1915+105 in the low hard state reveals for the first time in this source neutral K absorption edges from F…
Duality and Integrability of Two Dimensional String Effective Action
Ashok Das, J. Maharana, A. Melikyan
We present a prescription for constructing the monodromy matrix, , for invariant string effective actions and derive its transformation properties under t…

Bottom Quark Fragmentation in Top Quark Decay
Gennaro Corcella, Alexander D. Mitov
We study the fragmentation of the b quark in top decay in NLO QCD, within the framework of perturbative fragmentation, which allows one to resum large logarithms $\sim\log (m_t^2/m…
Two heads are better than two tapes
Tao Jiang, Joel Seiferas, Paul Vitanyi
We show that a Turing machine with two single-head one-dimensional tapes cannot recognize the set {x2x'| x \in {0,1}^* and x' is a prefix of x} in real time, although it can do so…
