Signatures of Spontaneous Breaking of R-Parity in Gluino Cascade Decays at LHC
A. Bartl, W. Porod, F. de Campos +4
We study the pattern of gluino cascade decays in a class of supersymmetric models where R-parity is spontaneously broken. We give a detailed discussion of the R-parity violating de…
Transverse momentum dependence in the perturbative calculation of pion form factor
Fu-Guang Cao, Tao Huang
By reanalysing transverse momentum dependence in the perturbative calculation of pion form factor an improved expression of pion form factor which takes into account the transverse…
Deep Inelastic Scattering with Tagged Photons at HERA
D. Bardin, L. Kalinovskaya, T. Riemann
We calculate cross-sections for neutral current deep inelastic scattering at HERA with photon tagging. Both the exact lowest-order cross-section and a leading logarithmic approxima…
Light-cone QCD predictions for elastic ed-scattering in the intermediate energy region
Jun Cao, Hui-fang Wu
The contributions of helicity-flip matrix elements to the deuteron form factors are discussed in the light-cone frame. Normalized , , and are ob…
Predictions for Anomalous tau+ tau- gamma Production at LEP 1
Jochen Biebel, Tord Riemann
We calculate distributions for tau+ tau- gamma production at LEP 1 taking into account a potentially existing anomalous magnetic moment a_tau of the tau lepton. The existing upper…
Asymmetric Quark/Antiquark Hadronization in e+e- Annihilation
S. J. Brodsky, B. -Q. Ma
We point out that the fragmentation of a strange quark into nucleons versus antinucleons is not necessarily identical , even though the per…
Probing Quartic Couplings Through Three Gauge Boson Production at an Linear Collider
S. Dawson, A. Likhoded, G. Valencia +1
We explore the capability of a 500 or 1000 GeV linear collider to measure anomalous quartic gauge boson couplings. In the framework of a non-linear effective Lagrangian wi…
QCD Sum Rules for The Double Ratio in HQET
Tao Huang, Zuo-Hong Li, Chuan-Wang Luo
The double ratio is calculated by QCD sum rules in heavy quark effective theory (HQET), both numerically and analytically. Our expression for…
Spinless Salpeter Equation: Laguerre Bounds on Energy Levels
Wolfgang Lucha, Franz F. Schöberl
The spinless Salpeter equation may be considered either as a standard approximation to the Bethe--Salpeter formalism, designed for the description of bound states within a relativi…
Search For Non-Standard Model CP/T violation At Tau-Charm Factory
T. Huang, W. Lu, Z. J. Tao
We systematically investigate the possibility of finding CP/T violation in the sector at Tau-Charm Factory. CP/T violation may occur at pair production process, expressed a…
Deuteron Electromagnetic Form Factors in the Intermediate Energy Region
Jun Cao, Hui-fang Wu
Based on a Perturbative QCD analysis of the deuteron form factor, a model for the reduced form factor is suggested. The numerical result is consistent with the data in the intermed…
Cold Strangelets Formation with Finite Size Effects in High Energy Heavy-Ion Collisions
Y. B. He, W. Q. Chao, C. S. Gao +1
We have studied the phase diagram and evolution of a strangelet in equilibrium with a finite hadronic gas. Significant finite size modifications of the phase diagram are found and…

Alfred Bartl, Helmut Eberl, Keisho Hidaka +3
We present a detailed study of the decays of the neutral Higgs bosons and within the Minimal Supersymmetric Standard Model. We find that the supersymmetric modes ${\til…

The ALEPH Collaboration
Indirect limits on the mass of the lightest neutralino are derived from the results of searches for charginos, neutralinos, and sleptons performed with data taken by the ALEPH Coll…

Wolfgang Lucha, Franz F. Schöberl
The Hamiltonian of the spinless relativistic Coulomb problem combines the standard Coulomb interaction potential with the square-root operator of relativistic kinematics. This Hami…
Z' Search in e+e- Annihilation
A. Leike, S. Riemann
Expectations for constraints on extra Z bosons are derived for LEP 2 and future linear e+e- colliders. For typical GUTs, a Z' with M_{Z'} \le 3 to 6 \sqrt{s} may cause observable e…

The DZero Collaboration, S. Abachi
We present results from a search for anomalous WW and WZ production in ppbar collisions at sqrt(s) = 1.8 TeV. We used ppbar->evjjX events observed during the 1992-1993 run of the F…

Bo-Qiang Ma, Andreas Schafer
The effect from quark masses and transversal motion on the Gottfried, Bjorken, and Ellis-Jaffe sum rules is examined by using a quark-parton model of nucleon structure functions ba…
