Study of dynamical supersymmetry breaking for the two dimensional lattice Wess-Zumino model
M. Beccaria, G. F. De Angelis, M. Campostrini +1
A new approach to the study of the transition point in a class of two dimensional Wess-Zumino models is presented. The method is based on the calculation of rigorous lower bounds o…
Weak lensing in scalar-tensor theories of gravity
Carlo Schimd, Jean-Philippe Uzan, Alain Riazuelo
This article investigates the signatures of various models of dark energy on weak gravitational lensing, including the complementarity of the linear and non-linear regimes. It inve…
Real symmetric random matrices and paths counting
Giovanni M. Cicuta
Exact evaluation of is here performed for real symmetric matrices of arbitrary order , up to some integer , where the matrix entries are independent iden…
Instantons, Fluxons and Open Gauge String Theory
Luca Griguolo, Domenico Seminara, Richard J. Szabo
We use the exact instanton expansion to illustrate various string characteristics of noncommutative gauge theory in two dimensions. We analyse the spectrum of the model and present…
Predictions and recent results in susy on the lattice
Alessandra Feo
In this brief review, I summarize the current theoretical knowledge in supersymmetry on the lattice, with special emphasis on recent results in the framework of N=1 supersymmetric…
Numerical Stochastic Perturbation Theory for full QCD
F. Di Renzo, L. Scorzato
We give a full account of the Numerical Stochastic Perturbation Theory method for Lattice Gauge Theories. Particular relevance is given to the inclusion of dynamical fermions, whic…
Double Scaling String Theory of QCD in Two Dimensions
L. Griguolo, D. Seminara, R. J. Szabo
We describe a novel double scaling limit of large N Yang-Mills theory on a two-dimensional torus and its relation to the geometry of the principal moduli spaces of holomorphic diff…
3-d lattice SU(3) free energy to four loops
F. Di Renzo, A. Mantovi, V. Miccio +2
We report on the perturbative computation of the 3d lattice Yang-Mills free energy to four loops by means of Numerical Stochastic Perturbation Theory. The known first and second or…
Two and three loops computations of renormalization constants for lattice QCD
F. Di Renzo, A. Mantovi, V. Miccio +2
Renormalization constants can be computed by means of Numerical Stochastic Perturbation Theory to two/three loops in lattice perturbation theory, both in the quenched approximation…
Exact supersymmetry on the lattice: the Wess-Zumino model
Marisa Bonini, Alessandra Feo
It is shown that the lattice Wess-Zumino model written in terms of Ginsparg-Wilson fermions is invariant under a generalized supersymmetry transformation which is determined by an…
Braneworld cosmology almost without branes
Gianluca Calcagni
We review some general aspects of braneworld cosmologies in which an inflationary period driven by a scalar field confined on the brane is described by a nonstandard effective Frie…
Information on the Super Yang-Mills Spectrum
A. Feo, P. Merlatti, F. Sannino
We investigate the spectrum of the lightest states of N=1 Super Yang-Mills. We first study the spectrum using the recently extended Veneziano Yankielowicz theory containing also th…
Two-Dimensional Yang-Mills Theory and Moduli Spaces of Holomorphic Differentials
L. Griguolo, D. Seminara, R. J. Szabo
We describe and solve a double scaling limit of large N Yang-Mills theory on a two-dimensional torus. We find the exact strong-coupling expansion in this limit and describe its rel…
The Nf=2 residual mass in Perturbative Lattice-HQET for an improved determination of the (MS bar) b-quark mass
Francesco Di Renzo, Luigi Scorzato
We determine to order alpha^3 the so-called residual mass in the lattice regularisation of the Heavy Quark Effective Theory for Nf=2. Our (gauge-invariant) strategy makes use of Nu…
Exact and semiclassical approach to a class of singular integral operators arising in fluid mechanics and quantum field theory
V. A. Fateev, R. De Pietri, E. Onofri
A class of singular integral operators, encompassing two physically relevant cases arising in perturbative QCD and in classical fluid dynamics, is presented and analyzed. It is sho…
Observational constraints on patch inflation in noncommutative spacetime
Gianluca Calcagni, Shinji Tsujikawa
We study constraints on a number of patch inflationary models in noncommutative spacetime using a compilation of recent high-precision observational data. In particular, the four-d…
Noncommutative models in patch cosmology
Gianluca Calcagni
We consider several classes of noncommutative inflationary models within an extended version of patch cosmological braneworlds, starting from a maximally invariant generalization o…
Consistency relations and degeneracies in (non)commutative patch inflation
Gianluca Calcagni
The consistency equations of patch inflation are considered in a next-to-leading-order slow-roll (SR) expansion. Some general aspects of braneworld degeneracy are pointed out, both…
Phase diagram of the lattice Wess-Zumino model from rigorous lower bounds on the energy
Matteo Beccaria, Massimo Campostrini, Gian Fabrizio De Angelis +1
We study the lattice N=1 Wess-Zumino model in two dimensions and we construct a sequence of exact lower bounds on its ground state energy density , converging to i…
Exact solution of BFKL equation in jet-physics
G. Marchesini, E. Onofri
It has been recently found that the heavy quark-antiquark QQbar pair multiplicity, in certain phase space region (QQbar at short distance, soft and with small velocity), satisfies…
