Spin chains and combinatorics

A. V. Razumov, Yu. G. Stroganov

In this letter we continue the investigation of finite XXZ spin chains with periodic boundary conditions and odd number of sites, initiated in paper \cite{S}. As it turned out, for…

Hopf solitons and area preserving diffeomorphisms of the sphere

L. A. Ferreira, A. V. Razumov

We consider a (3+1)-dimensional local field theory defined on the sphere. The model possesses exact soliton solutions with non trivial Hopf topological charges, and infinite number…

Lagrangian Noether symmetries as canonical transformations

J. Antonio García, J. M. Pons

We prove that, given a time-independent Lagrangian defined in the first tangent bundle of configuration space, every infinitesimal Noether symmetry that is defined in the $n$ -tange…

Radiative VPgamma transitions and eta-eta' mixing

A. Bramon, R. Escribano, M. D. Scadron

A value for the $η$ - $η^{'}$ mixing angle is extracted from the data on $V P γ$ transitions using simple quark-model ideas. The set of data covers {\it all} possible radiative tran…

Optimal encoding and decoding of a spin direction

E. Bagan, M. Baig, A. Brey +2

For a system of N spins 1/2 there are quantum states that can encode a direction in an intrinsic way. Information on this direction can later be decoded by means of a quantum measu…

Quantum Zeno and anti-Zeno effects in the Friedrichs model

I. Antoniou, E. Karpov, G. Pronko +1

We analyze the short-time behavior of the survival probability in the frame of the Friedrichs model for different formfactors. We have shown that this probability is not necessary…

Communication of Spin Directions with Product States and Finite Measurements

E. Bagan, M. Baig, R. Munoz-Tapia

Total spin eigenstates can be used to intrinsically encode a direction, which can later be decoded by means of a quantum measurement. We study the optimal strategy that can be adop…

Centrality Dependence of Charged Particle Multiplicity in Au-Au Collisions at sqrt(s_NN)=130 GeV

PHENIX Collaboration, K. Adcox

We present results for the charged-particle multiplicity distribution at mid-rapidity in Au - Au collisions at sqrt(s_NN)=130 GeV measured with the PHENIX detector at RHIC. For the…

The scaling evolution of cosmological constant

Ilya L. Shapiro, Joan Sola

In quantum field theory the parameters of the vacuum action are subject to renormalization group running. In particular, the ``cosmological constant'' is not a constant in a quantu…

Nonlinear Supersymmetry, Quantum Anomaly and Quasi-Exactly Solvable Systems

Sergey Klishevich, Mikhail Plyushchay

The nonlinear supersymmetry of one-dimensional systems is investigated in the context of the quantum anomaly problem. Any classical supersymmetric system characterized by the nonli…

Chromomagnetic Catalysis of Color Superconductivity in a (2+1)-dimensional NJL Model

D. Ebert, K. G. Klimenko, H. Toki

The influence of a constant uniform external chromomagnetic field $H$ on the formation of color superconductivity has been investigated. The consideration was performed in the fram…

A Quasi-Model-Independent Search for New High p_T Physics at DZero

DZero Collaboration

We apply a quasi-model-independent strategy ("Sleuth") to search for new high p_T physics in approximately 100 pb^-1 of ppbar collisions at sqrt(s) = 1.8 TeV collected by the DZero…

Inclusive Particle Production at LEP

V. Uvarov

New results on inclusive production of Sigma^- and Lambda(1520) and on proton production in quark and gluon jets are presented. These results are based on 2 million hadronic Z deca…

Is the chiral U(1) theory trivial?

V. Bornyakov, A. Hoferichter, G. Schierholz

The chiral U(1) theory differs from the corresponding vector theory by an imaginary contribution to the effective action which amounts to a phase factor in the partition function.…

Loop Induced Flavor Changing Neutral Decays of the Top Quark in a General Two-Higgs-Doublet Model

Santi Bejar, Jaume Guasch, Joan Sola

Decays of the top quark induced by flavor changing neutral currents (FCNC) are known to be extremely rare events within the Standard Model. This is so not only for the decay modes…
