On the evaluation of the improvement parameter in the lattice Hamiltonian approach to critical phenomena
Massimo Campostrini, Pietro Parruccini, Paolo Rossi
In lattice Hamiltonian systems with a quartic coupling , a critical value may exist such that, when , the leading irrelevant operator decouples from the Hamiltonian…
Three-Nucleon Electroweak Capture Reactions
L. E. Marcucci, M. Viviani, A. Kievsky +2
Recent advances in the study of the p-d radiative and mu-3he weak capture processes are presented and discussed. The three-nucleon bound and scattering states are obtained using th…
A unique spinodal region in asymmetric nuclear matter
J. Margueron, P. Chomaz
Asymmetric nuclear matter at sub-saturation densities is shown to present only one type of instabilities. The associated order parameter is dominated by the isoscalar density and s…
Mathematical structure of the temporal gauge
J. Loeffelholz, G. Morchio, F. Strocchi
The mathematical structure of the temporal gauge of QED is critically examined in both the alternative formulations characterized by either positivity or regularity of the Weyl alg…
Almost Conformal Vacua and Confinement
Roberto Auzzi, Roberto Grena, Kenichi Konishi
Dynamics of confining vacua which appear as deformed superconformal theory with a non-Abelian gauge symmetry, is studied by taking a concrete example of the sextet vacua of ${\cal…
Transverse Fluctuations in the Driven Lattice Gas
Sergio Caracciolo, Andrea Gambassi, Massimiliano Gubinelli +1
We define a transverse correlation length suitable to discuss the finite-size-scaling behavior of an out-of-equilibrium lattice gas, whose correlation functions decay algebraically…
Search for Long-lived Charged Massive Particles in anti-p p Collisions at s**1/2 = 1.8 TeV
D. Acosta
We report a search for production of long-lived charged massive particles in a data sample of 90 pb^{-1} of \sqrt{s} = 1.8 TeV p anti-p collisions recorded by the Collider Detector…
IIB Soliton Spectra with All Fluxes Activated
Jarah Evslin
Building upon an earlier proposal for the classification of fluxes, a sequence is proposed which generalizes the AHSS by computing type IIB string theory's group of conserved RR an…
The Search for the Sidereal and Solar Diurnal Modulations in the Total MACRO Muon Data Set
The MACRO Collaboration, M. Ambrosio
We have analyzed 44.3M single muons collected by MACRO from 1991 through 2000 in 2,145 live days of operation. We have searched for the solar diurnal, apparent sidereal, and pseudo…
Neutrino mean free path and in-medium nuclear interaction
J. Margueron, J. Navarro, N. Van Giai
Neutrinos produced during the collapse of a massive star are trapped in a nuclear medium (the proto-neutron star). Typically, neutrino energies (10-100 MeV) are of the order of nuc…
Representations of the Heisenberg algebra on holomorphic functions and Krein structures
M. Mnatsakanova, G. Morchio, F. Strocchi +1
Representations of CCR algebras in spaces of entire functions are classified on the basis of isomorphisms between the Heisenberg CCR algebra A_H and star algebras of holomorphic op…
Precise measurements of the KS->gamma gamma and KL->gamma gamma decay rates
A. Lai
The KS->gamma gamma decay rate has been measured with the NA48 detector using a high intensity short neutral beam from the CERN SPS. The measured branching ratio BR(KS->gamma gamma…
SUSY vs E8 Gauge Theory in 11 Dimensions
Jarah Evslin, Hisham Sati
Diaconescu, Moore and Witten have shown that the topological part of the M-theory partition function is an invariant of an E8 gauge bundle over the 11-dimensional bulk. This presen…
Higgs- and quark-inspired modifications of the finite-temperature properties of the Polyakov model
D. Antonov
(2+1)-dimensional Georgi-Glashow model, else called the Polyakov model, is explored at nonzero temperatures and in the regime when the Higgs boson is not infinitely heavy. The fini…
Inequalities for trace anomalies, length of the RG flow, distance between the fixed points and irreversibility
Damiano Anselmi
I discuss several issues about the irreversibility of the RG flow and the trace anomalies c, a and a'. First I argue that in quantum field theory: i) the scheme-invariant area Delt…
Predictions of the most minimal see-saw model
M. Raidal, A. Strumia
We derive the most minimal see-saw texture from an extra-dimensional dynamics. It predicts theta_13 = 0.078 \pm 0.015 and m_ee = 2.6 \pm 0.4 meV. Assuming thermal leptogenesis, the…
Gamma Ray Large Area Space Telescope (GLAST) Balloon Flight Data Handling Overview
T. H. Burnett, A. Chekhtman, E. do Couto e Silva +22
The GLAST Balloon Flight Engineering Model (BFEM) represents one of 16 towers that constitute the Large Area Telescope (LAT), a high-energy (>20 MeV) gamma-ray pair-production tele…
Multicritical phenomena in O(n_1)+O(n_2)-symmetric theories
Pasquale Calabrese, Andrea Pelissetto, Ettore Vicari
We study the multicritical behavior arising from the competition of two distinct types of ordering characterized by O(n) symmetries. For this purpose, we consider the renormalizati…
Exact Witten Index in D=2 supersymmetric Yang-Mills quantum mechanics
Massimo Campostrini, Jacek Wosiek
A new, recursive method of calculating matrix elements of polynomial hamiltonians is proposed. It is particularly suitable for the recent algebraic studies of the supersymmetric Ya…
Free energy and theta dependence of SU(N) gauge theories
L. Del Debbio, H. Panagopoulos, E. Vicari
We study the dependence of the free energy on the CP violating angle theta, in four-dimensional SU(N) gauge theories with N >= 3, and in the large-N limit. Using the Wilson lattice…
Functional approach to 2+1 dimensional gravity coupled to particles
Luigi Cantini, Pietro Menotti
The quantum gravity problem of N point particles interacting with the gravitational field in 2+1 dimensions is approached working out the phase-space functional integral. The maxim…
Scattering in the Presence of a Reflecting and Transmitting Impurity
M. Mintchev, E. Ragoucy, P. Sorba
We investigate factorized scattering from a reflecting and transmitting impurity. Bulk scattering is non trivial, provided that the bulk scattering matrix depends separately on the…
Deconfining transition in Full QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We present evidence that in full QCD with two dynamical quarks confinement is produced by dual superconductivity of the vacuum as in the quenched theory. Preliminary information is…
Color confinement and dual superconductivity in unquenched QCD
J. M. Carmona, M. D'Elia, L. Del Debbio +4
We report on evidence from lattice simulations that confinement is produced by dual superconductivity of the vacuum in full QCD as in quenched QCD. Preliminary information is obtai…
