Towards the solution of noncommutative : Morita equivalence and large N-limit
L. Griguolo, D. Seminara, P. Valtancoli
In this paper we shall investigate the possibility of solving U(1) theories on the non-commutative (NC) plane for arbitrary values of by exploiting Morita equivalence. This dua…
The APENEXT project
F. Bodin, P. Boucaud, N. Cabibbo +31
APENEXT is a new generation APE processor, optimized for LGT simulations. The project follows the basic ideas of previous APE machines and develops simple and cheap parallel system…
The target space dependence of the Hagedorn temperature
G. Grignani, M. Orselli, G. W. Semenoff
The effect of certain simple backgrounds on the Hagedorn temperature in theories of closed strings is examined. The background of interest are constant Neveu-Schwarz -fields, a…
Comparison of Phase Space Slicing and Dipole Subtraction Methods for gamma^* -> Q Qbar
Tim Oliver Eynck, Eric Laenen, Lukas Phaf +1
We compare the phase space slicing and dipole subtraction methods in the computation of the inclusive and differential next-to-leading order cross sections for heavy quark producti…
Nested Sums, Expansion of Transcendental Functions and Multi-Scale Multi-Loop Integrals
Sven Moch, Peter Uwer, Stefan Weinzierl
Expansion of higher transcendental functions in a small parameter are needed in many areas of science. For certain classes of functions this can be achieved by algebraic means. The…
Soft-Gluon Resummation for the Fragmentation of Light and Heavy Quarks at Large x
M. Cacciari, S. Catani
We present a QCD study of fragmentation processes for light and heavy quarks in the semi-inclusive region of large x. Large logarithmic terms, due to soft-gluon radiation, are eval…
On the Detection of a Scalar Stochastic Background of Gravitational Waves
D. Babusci, L. Baiotti, F. Fucito +1
In the near future we will witness the coming to a full operational regime of laser interferometers and resonant mass detectors of spherical shape. In this work we study the sensit…
On the unitarity of quantum gauge theories on non-commutative spaces
A. Bassetto, L. Griguolo, G. Nardelli +1
We study the perturbative unitarity of non-commutative quantum Yang-Mills theories, extending previous investigations on scalar field theories to the gauge case where non-locality…
A general algorithm to generate unweighted events for next-to-leading order calculations in electron-positron annihilation
Stefan Weinzierl
Given a next-to-leading order calculation, we show how to set up a computer program, which generates a sequence of unweighted momentum configurations, each configuration containing…
Transverse Momentum Distributions in B-Decays
U. Aglietti, R. Sghedoni, L. Trentadue
We consider transverse momentum distributions in B-decays. The O(alpha_S) coefficients for soft and collinear logarithms are computed to next-to-leading accuracy. Resummation of la…
Exclusive Decay Amplitudes from Light-Cone Sum Rules
R. Rückl, S. Weinzierl, O. Yakovlev
We review recent developments in QCD sum rule applications to semileptonic B->pi and D->pi transitions.
Background field method in the Wilson formulation
M. Bonini, E. Tricarico
A cutoff regularization for a pure Yang-Mills theory is implemented within the background field method keeping explicit the gauge invariance of the effective action. The method has…
Wilsonian Renormalization Group and the Non-Commutative IR/UV Connection
Luca Griguolo, Massimo Pietroni
We study the IR/UV connection of the four-dimensional non-commutative phi^4 theory by using the Wilsonian Renormalization Group equation. Extending the usual formulation to the non…
Matrix strings in a B-field
Gianluca Grignani, Marta Orselli, Gordon W. Semenoff
We study the discrete light-cone quantization (DLCQ) of closed strings in the background of Minkowski space-time and a constant Neveu-Schwarz -field. For the Bosonic string, we…
The structure of radiatively induced Lorentz and CPT violation in QED at finite temperature
L. Cervi, L. Griguolo, D. Seminara
We obtain the induced Lorentz- and CPT-violating term in QED at finite temperature using imaginary-time formalism and dimensional regularization. Its form resembles a Chern-Simons-…
Hard Non-commutative Loops Resummation
Luca Griguolo, Massimo Pietroni
The non-commutative version of the euclidean theory is considered. By using Wilsonian flow equations the ultraviolet renormalizability can be proved to all orders in pertu…
Dipole formalism with heavy fermions
Lukas Phaf, Stefan Weinzierl
We extend the dipole formalism of Catani and Seymour to QCD processes involving heavy fermions. We give the appropriate subtraction terms together with their integrated counterpart…
