X-ray Imaging Using a Hybrid Photon Counting GaAs Pixel Detector

C. Schwarz, M. Campbell, R. Goeppert +11

The performance of hybrid GaAs pixel detectors as X-ray imaging sensors were investigated at room temperature. These hybrids consist of 300 mu-m thick GaAs pixel detectors, flip-ch…

Yangians, finite W-algebras and the Non Linear Schrodinger hierarchy

M. Mintchev, E. Ragoucy, P. Sorba +1

We show an algebra morphism between Yangians and some finite W-algebras. This correspondence is nicely illustrated in the framework of the Non Linear Schrodinger hierarchy. For suc…

Limits on dark matter WIMPs using upward-going muons in the MACRO detector

The MACRO Collaboration, M. Ambrosio et al

We perform an indirect search for Weakly Interacting Massive Particles (WIMPs) using the MACRO detector to look for neutrino-induced upward-going muons resulting from the annihilat…

Determination of the exponent gamma for SAWs on the two-dimensional Manhattan lattice

Sergio Caracciolo, Maria Serena Causo, Peter Grassberger +1

We present a high-statistics Monte Carlo determination of the exponent gamma for self-avoiding walks on a Manhattan lattice in two dimensions. A conservative estimate is $γ\gtappro…

Testing the efficiency of different improvement programs

Sergio Caracciolo, Andrea Montanari, Andrea Pelissetto

We study the finite-size behaviour of a tree-level on-shell improved action for the N-vector model. We present numerical results for N=3 and analytic results in the large-N limit f…

Fermion masses and symmetry breaking of a U(2) flavour symmetry

Riccardo Barbieri, Leonardo Giusti, Lawrence J. Hall +1

We show how a specific sequential breaking pattern of a U(2) flavour symmetry occurs automatically in a broad framework. The relative orientation in U(2) space of the spurion field…

Precise tests of a quark mass texture

Riccardo Barbieri, Lawrence J. Hall, Andrea Romanino

The relations $∣ V_{u b} / V_{c b} ∣ = (m_{u} / m_{c})^{1/2}$ and $∣ V_{t d} / V_{t s} ∣ = (m_{d} / m_{s})^{1/2}$ between the CKM matrix elements and the quark masses are shown to imply a remarkably precise d…

The Nonlinear Schrodinger Equation on the Half Line

M. Gattobigio, A. Liguori, M. Mintchev

The nonlinear Schrodinger equation on the half line with mixed boundary condition is investigated. After a brief introduction to the corresponding classical boundary value problem,…

Search for the Standard Model Higgs boson at the LEP2 collider near sqrt(S) = 183GeV

ALEPH Collaboration

During 1997 the ALEPH experiment at LEP gathered 57pb^-1 of data at centre-of- mass energies near 183 GeV. These data are used to look for possible signals from the production of t…

D-branes and Cosmology

Michele Maggiore, Antonio Riotto

D-branes, topological defects in string theory on which string endpoints can live, may give new insight into the understanding of the cosmological evolution of the Universe at earl…

Study of D0-Dbar0 mixing and D0 doubly cabibbo-suppressed decays

ALEPH collaboration

Using a sample of four million hadronic Z events collected in ALEPH from 1991 to 1995, the decays D*+ -> D0pi^+_s, with D0 decaying to K-pi+ or to K+pi-, are studied. The relative…

Bubble-nucleation rates for radiatively induced first-order phase transitions

Alessandro Strumia, Nikolaos Tetradis

We present a consistent calculation of bubble-nucleation rates in theories of two scalar fields. Our approach is based on the notion of a coarse-grained free energy that incorporat…

Natural ranges of supersymmetric signals

L. Giusti, A. Romanino, A. Strumia

The LEP2 experiments pose a serious naturalness problem for supersymmetric models. The problem is stronger in gauge mediation than in supergravity models. Particular scenarios, lik…

Search for a Technicolor omega_T Particle in Events with a Photon and a b-quark Jet at CDF

The CDF Collaboration, F. Abe

If the Technicolor omega_T particle exists, a likely decay mode is omega_T -> gamma pi_T, followed by pi_T -> bb-bar, yielding the signature gamma bb-bar. We have searched 85 pb^-1…

Measurement of the Top Quark Mass with the Collider Detector at Fermilab

F. Abe, CDF Collaboration

We present a new measurement of the top quark mass in $t t ˉ$ events in which both $W$ bosons from top quarks decay into lepton ( $e ν, μν$ ). We use events collected by the CDF exp…

Strange Stars with Realistic Quark Vector Interaction and Phenomenological Density-dependent Scalar Potential

Mira Dey, Ignazio Bombaci, Jishnu Dey +2

We derive an equation of state (EOS) for strange matter, starting from an interquark potential which (i) has asymptotic freedom built into it, (ii) shows confinement at zero baryon…

The leading chiral electromagnetic correction to the nonleptonic Delta I = 3/2 amplitude in kaon decays

Vincenzo Cirigliano, John F. Donoghue, Eugene Golowich

In kaon decay, electromagnetic radiative corrections can generate shifts in the apparent Delta I = 3/2 amplitude of order alpha A_0/A_2 ~ 22 alpha. In order to know the true Delta…

Crossover scaling from classical to non-classical critical behaviour

Sergio Caracciolo, Maria Serena Causo, Andrea Pelissetto +2

Interacting physical systems in the neighborhood of criticality (and massive continuum field theories) can often be characterized by just two physical scales: a (macroscopic) corre…
