The Seiberg-Witten prepotential and the Euler class of the reduced moduli space of instantons
R. Flume, R. Poghossian, H. Storch
The n-instanton contribution to the Seiberg-Witten prepotential of N=2 supersymmetric d=4 Yang Mills theory is represented as the integral of the exponential of an equivariantly ex…
Search for Leptoquarks in Electron-Photon Scattering at sqrt(s_ee) up to 209 GeV at LEP
The OPAL collaboration, G. Abbiendi
Searches for first generation scalar and vector leptoquarks, and for squarks in R-parity violating SUSY models with the direct decay of the squark into Standard Model particles, ha…
Identifying Complexity by Means of Matrices
S. Drozdz, J. Kwapien, J. Speth +1
Complexity is an interdisciplinary concept which, first of all, addresses the question of how order emerges out of randomness. For many reasons matrices provide a very practical an…
The Coupled Cluster Method in Hamiltonian Lattice Field Theory: SU(2) Glueballs
A. Wichmann, D. Schuette, B. C. Metsch +1
The glueball spectrum within the Hamiltonian formulation of lattice gauge theory (without fermions) is calculated for the gauge group SU(2) and for two spatial dimensions. The Hilb…
Parameterised models for the lensing cluster Abell 1689
Lindsay King, Douglas Clowe, Peter Schneider
Here we apply a recently developed maximum likelihood method for determining best-fit parameterised lens models to observations of the rich lensing cluster Abell 1689. The observat…
Laplace operators in deRham complexes associated with measures on configuration spaces
S. Albeverio, A. Daletskii, Y. Kondratiev +1
Let denote the space of all locally finite configurations in a complete, stochastically complete, connected, oriented Riemannian manifold , whose volume measure is inf…
Fermion and boson random point processes as particle distributions of infinite free Fermi and Bose gases of finite density
E. Lytvynov
The aim of this paper is to show that fermion and boson random point processes naturally appear from representations of CAR and CCR which correspond to gauge invariant generalized…
Bounds on Broken R-Parity from Leptonic Meson Decays
Herbi Dreiner, Giacomo Polesello, Marc Thormeier
Investigating leptonic decays of pi^-, K^-, B^-, pi^0, K_L^0, B_s^0 we present new bounds on some products of two R-parity violating coupling constants. For mesons of a similar str…
B-modes in cosmic shear from source redshift clustering
P. Schneider, L. van Waerbeke, Y. Mellier
Weak gravitational lensing by the large scale structure can be used to probe the dark matter distribution in the Universe directly and thus to probe cosmological models. The recent…
B1422+231: The influence of mass substructure on strong lensing
M. Bradac, P. Schneider, M. Steinmetz +3
In this work we investigate the gravitationally lensed system B1422+231. High--quality VLBI image positions, fluxes and shapes as well as an optical HST lens galaxy position are us…
Nonthermal production of gravitinos and inflatinos in the Inflationary Universe
Hans Peter Nilles, Marco Peloso
The success of primordial nucleosynthesis imposes stringent bounds on the abundance of gravitational relics. This is particularly true for gravitinos, which - for models with gravi…
Detection of an Iron Emission Feature from the Lensed BAL QSO H1413+117 at z=2.56
T. Oshima, K. Mitsuda, R. Fujimoto +8
We present the X-ray energy spectrum of the lensed BAL QSO H1413+117 (the Cloverleaf) at z=2.56 observed with the Chandra X-ray observatory. We detected 293 photons in a 40 ks Adva…
The noise of cluster mass reconstructions from a source redshift distribution
Marco Lombardi, Peter Schneider, Carlos Morales-Merino
The parameter-free reconstruction of the surface-mass density of clusters of galaxies is one of the principal applications of weak gravitational lensing. From the observable ellipt…
Search for Doubly Charged Higgs Bosons with the OPAL detector at LEP
The OPAL collaboration, G. Abbiendi
A search for pair-produced doubly charged Higgs bosons has been performed using data samples corresponding to an integrated luminosity of about 614 pb-1 collected with the OPAL det…
A search for radio supernovae and supernova remnants in the region of NGC1569's super star clusters
A. Greve, A. Tarchi, S. Huettemeister +4
We have used MERLIN, at 1.4 and 5 GHz, to search for radio supernovae (RSNe) and supernova remnants (SNRs) in the unobscured irregular dwarf galaxy NGC1569, and in particular in th…
Extended HI disks in dust-lane elliptical galaxies
T. A. Oosterloo, R. Morganti, E. M. Sadler +2
We present the results of HI observations of five dust-lane ellipticals with the Australia Telescope Compact Array. Two galaxies (NGC 3108 and NGC 1947) are detected, and sensitive…
A precision calculation of the effective number of cosmological neutrinos
G. Mangano, G. Miele, S. Pastor +1
The neutrino energy density of the Universe can be conveniently parametrized in terms of the so-called effective number of neutrinos, N_nu^eff. This parameter enters in several cos…
Parity Doublets from a Relativistic Quark Model
Ulrich Loering, Bernard Metsch
The Nucleon- and the Lambda-excitation spectrum exhibit parity doublets, i.e. states of the same spin but with opposite parity being almost degenerate in mass. It is shown that in…
Calculating the anomalous supersymmetry breaking in Super-Yang-Mills theories with local coupling
Elisabeth Kraus
Supersymmetric Yang-Mills-theories with local gauge coupling have a new type of anomalous breaking, which appears as a breaking of supersymmetry in the Wess-Zumino-gauge. The anoma…
The Interacting Dwarf Galaxy NGC 3077: The Interplay of Atomic and Molecular Gas with Violent Star Formation
F. Walter, A. Weiss, C. Martin +1
We present a comprehensive multi-wavelength study of the nearby interacting dwarf galaxy NGC3077 (member of the M81 triplet). High resolution VLA HI observations show that most of…
Derivatives of Eisenstein series and Faltings heights
S. Kudla, M. Rapoport, T. Yang
We prove a relation between a generating series for the heights of Heegner cycles on the arithmetic surface associated to a Shimura curve and the second term in the Laurent expansi…

R. Flume, R. Poghossian, H. Storch
The -instanton contribution to the Seiberg-Witten prepotential of supersymmetric Yang Mills theory is represented as the integral of the exponential of an equi…
Noncommutative spin-1/2 representations
J. M. Grimstrup, H. Grosse, E. Kraus +3
In this letter we apply the methods of our previous paper hep-th/0108045 to noncommutative fermions. We show that the fermions form a spin-1/2 representation of the Lorentz algebra…
