Possible improvements on the mass of the tau neutrino using leptonic decays

S. Pakvasa, K. Zuber

We show how a very accurate measurement of the branching ratios of the leptonic decay modes of the mesons can lead to a significant improvement in the mass limit for the…

Continuum methods in lattice perturbation theory

Thomas Becher, Kirill Melnikov

We show how methods of continuum perturbation theory can be used to simplify perturbative lattice calculations. We use the technique of asymptotic expansions to expand lattice loop…

NLO Higgs boson rapidity distribution at hadron colliders

Charalampos Anastasiou, Lance Dixon, Kirill Melnikov

We describe a new method, based on an extension of the unitarity cutting rules proposed earlier, which is very efficient for the algorithmic evaluation of phase-space integrals for…

Are supersymmetric models with large tan(beta) natural ?

Howard Baer, Javier Ferrandis, Xerxes Tata

We point out that, contrary to general belief, generic supersymmetric models are not technically unnatural in the limit of very large values of the parameter tan(beta) when radiati…

Mass predictions based on a supersymmetric SU(5) fixed point

Javier Ferrandis

I examine the possibility that the third generation fermion masses are determined by an exact fixed point of the minimal supersymmetric SU(5) model. When one-loop supersymmetric th…

Decay of High-Energy Astrophysical Neutrinos

John F. Beacom, Nicole F. Bell, Dan Hooper +2

Existing limits on the non-radiative decay of one neutrino to another plus a massless particle (e.g., a singlet Majoron) are very weak. The best limits on the lifetime to mass rati…

Updated Constraints on the Minimal Supergravity Model

H. Baer, C. Balazs, A. Belyaev +3

Recently, refinements have been made on both the theoretical and experimental determinations of the i.) mass of the lightest Higgs scalar, ii.) relic density of cold dark matter in…

A Measurement of Psi(2S) Resonance Parameters

BES Collaboration, J. Z. Bai

Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been measured in the vicinity of the Psi(2S) resonance using the BESII detector operated at the BEPC. The Psi(2S) t…

Higgs-mediated leptonic decays of B_s and B_d mesons as probes of supersymmetry

J. K. Mizukoshi, Xerxes Tata, Yili Wang

If tan(beta) is large, down-type quark mass matrices and Yukawa couplings cannot be simultaneously diagonalized, and flavour violating couplings of the neutral Higgs bosons are ind…

Relating bottom quark mass in DR-bar and MS-bar regularization schemes

H. Baer, J. Ferrandis, K. Melnikov +1

The value of the bottom quark mass at M_Z in the DR-bar scheme is an important input for the analysis of supersymmetric models with a large value of tan(beta). Conventionally, howe…

Yet Another Extension of the Standard Model: Oases in the Desert?

J. D. Bjorken, S. Pakvasa, S. F. Tuan

We have searched for conceptually simple extensions of the standard model, and describe here a candidate model which we find attractive. Our starting point is the assumption that o…

X. -G. He, C. -P. Kao, J. P. Ma +1

In this paper we investigate the possibility of studying form factor using the semi-inclusive decays . In general semi-inclusive decays i…

Lepton number violating muon decay and the LSND neutrino anomaly

K. S. Babu, Sandip Pakvasa

We show that lepton number violating muon decays, μ^+ -> e^+ + ν_e-bar + ν_i-bar (i=e, μor τ), can consistently explain the neutrino anomaly reported by the LSND experiment. Two ef…
