Light Quenched Hadron Spectrum and Decay Constants on different Lattices
C. R. Allton, V. Gimenez, L. Giusti +1
In this paper we study O(2000) (quenched) lattice configurations from the APE collaboration, for different lattice volumes and for 6.0 \le beta \le 6.4 using both the Wilson and th…
Critical limit and anisotropy in the two-point correlation function of three-dimensional O(N) models
Massimo Campostrini, Andrea Pelissetto, Paolo Rossi +1
In three-dimensional O(N) models, we investigate the low-momentum behavior of the two-point Green's function G(x) in the critical region of the symmetric phase. We consider physica…
On gravitational waves emitted by an ensemble of rotating neutron stars
A. Giazotto, S. Bonazzola, E. Gourgoulhon
We study the possibility to detect the gravitational wave background generated by all the neutron stars in the Galaxy with only one gravitational wave interferometric detector. The…
An Improved Measurement of the Left-Right Z0 Cross Section Asymmetry
SLD Collaboration, K. Abe, I. Abt et al
We present a new measurement of the left-right cross section asymmetry (ALR) for Z boson production by e+e- collisions. The measurement was performed at a center-of-mass energy of…
Towards a non-singular pre-big bang cosmology
M. Gasperini, M. Maggiore, G. Veneziano
We discuss general features of the -function equations for spatially flat, -dimensional cosmological backgrounds at lowest order in the string-loop expansion, but to all…
Naturalness constraints on gauge-mediated supersymmetry breaking models
Gautam Bhattacharyya, Andrea Romanino
The question of naturalness is addressed in the context of gauge-mediated supersymmetry breaking models. Requiring that arises naturally imposes upper limits on the right-han…
Naturalness bounds on gauge mediated soft terms
Paolo Ciafaloni, Alessandro Strumia
After a general discussion about the quantitative meaning of the naturalness upper bounds on the masses of supersymmetric particles, we compute these bounds in models with gauge-me…
Electric dipole moments from Yukawa phases in supersymmetric theories
Andrea Romanino, Alessandro Strumia
We study quark and electron EDMs generated by Yukawa couplings in supersymmetric models with different gauge groups, using the EDM properties under flavour transformations. In the…
Unified Theories with U(2) Flavor Symmetry
R. Barbieri, L. J. Hall, S. Raby +1
A general operator expansion is presented for quark and lepton mass matrices in unified theories based on a U(2) flavor symmetry, with breaking parameter of order $V_{cb} \approx m…
Comparing Different Improvement Programs for the N-Vector Model
Sergio Caracciolo, Andrea Pelissetto
We discuss the connection between various types of improved actions in the context of the two-dimensional sigma-model. We also discuss spectrum-improved actions showing that these…
NLO Quarkonium Production in Hadronic Collisions
M. L. Mangano, A. Petrelli
We present some preliminary results on the next-to-leading order calculation in QCD of quarkonium production cross sections in hadronic collisions. We will show that the NLO total…
(1+1)-dimensional turbulence
R. Benzi, L. Biferale, R. Tripiccione +1
A class of dynamical models of turbulence living on a one-dimensional dyadic-tree structure is introduced and studied. The models are obtained as a natural generalization of the po…
Topological charge on the lattice: a field theoretical view of the geometrical approach
Leonardo Rastelli, Paolo Rossi, Ettore Vicari
We construct sequences of ``field theoretical'' (analytical) lattice topological charge density operators which formally approach geometrical definitions in 2-d models a…
First Measurement of the Left-Right Charge Asymmetry in Hadronic Z Boson Decays and a New Determination of sin^2(theta_eff)
SLD Collaboration, K. Abe, I. Abt
We present the first measurement of the left-right charge asymmetry A_Q^{obs} in hadronic Z boson decays. This was performed at E_cm = 91.27 GeV with the SLD at the SLAC Linear Col…
Measurement of Dijet Angular Distributions at CDF
F. Abe
We have used 106 pb^-1 of data collected in proton-antiproton collisions at sqrt(s)=1.8 TeV by the Collider Detector at Fermilab to measure jet angular distributions in events with…
The inclusive transverse response of nuclear matter
A. Fabrocini
The electromagnetic inclusive transverse response of nuclear matter at saturation density is studied within the correlated basis function perturbation theory for momentum transfers…
The three-loop beta function in SU(N) lattice gauge theories
B. Alles, A. Feo, H. Panagopoulos
We calculate the third coefficient of the lattice function in pure Yang-Mills theory. We make use of a computer code for solving perturbation theory analytically on the lattice…
Radiatively induced light right-handed stop
Alessandro Strumia
A right-handed stop not much heavier or even lighter than the Z boson has today desirable phenomenological consequences. We study how it can result within the usual radiative scena…
Light Quenched Hadron Spectrum and Decay Constants on different Lattices
C. R. Allton, V. Gimenez, L. Giusti +1
We present a study of (quenched) lattice configurations from the APE collaboration, for using both the Wilson and the SW-Clover fermion action. We…
-parity-Violating Supersymmetric Yukawa Couplings: A Mini-review
