Measurement of the form-factor ratios for D_s^+ -> phi ell^+ nu_ell

Fermilab E791 Collaboration, E. M. Aitala, S. Amato

We have measured the form factor ratios r_V = V(0)/A_1(0) and r_2 = A_2(0)/A_1(0) for the decay D_s^+ -> phi ell^+ nu_ell, phi -> K^+ K^-, using data from charm hadroproduction exp…

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…

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…

Measurement of the Ds Lifetime

Fermilab E791 Collaboration, E. M. Aitala

We report the results of a precise measurement of the Ds meson lifetime based on 1662 +/- 56 fully reconstructed Ds -> phi pi decays, from the charm hadroproduction experiment E791…

Search for Selectron and Squark Production in Collisions at HERA

ZEUS Collaboration

We have searched for the production of a selectron and a squark in collisions at a center-of-mass energy of 300 GeV using the ZEUS detector at HERA. The selectron and squark…

Production of pi+, K+, K0, K*0, phi, p and Lambda-0 in Hadronic Z0 Decays

The SLD Collaboration, K. Abe

We have measured the differential production cross sections as a function of scaled momentum x_p=2p/E_cm of the identified hadron species pi+, K+, K0, K*0, phi, p, Lambda0, and of…

An Improved Test of the Flavor Independence of Strong Interactions

K. Abe et al

We present an improved comparison of the strong coupling of the gluon to light (q_l=u+d+s), c, and b quarks, determined from multijet rates in flavor-tagged samples of hadronic Z0…

Search for a new gauge boson in decays

The NOMAD Collaboration, J. Altegoer et al

A search was made for a new light gauge boson which might be produced in decay from neutral pions generated by 450-GeV protons in the CERN SPS neutrino target. T…
