Charmonium Spectroscopy (X,Y,Z) at the B Factories

Michal Kreps

Since 2003 several states in the charmonium mass region were discovered. While in the conventional c c-bar spectrum some states are missing, the number of states observed up to now…

Tevatron Experimental Issues at High Luminosities

Michal Kreps

In this paper we describe the detector components, triggers and analysis techniques for flavor physics at the Tevatron experiments CDF and DO. As Tevatron performs very well and ru…

Search for the QCD critical point at SPS energies

NA49 Collaboration, SHINE Collaboration

Lattice QCD calculations locate the QCD critical point at energies accessible at the CERN Super Proton Synchrotron (SPS). We present average transverse momentum and multiplicity fl…

Measurement of Inclusive Radiative B-meson Decays with a Photon Energy Threshold of 1.7 GeV

A. Limosani

Using 605/fb of data collected at the Upsilon(4S) resonance we present a measurement of the inclusive radiative B-meson decay channel, B to X_s gamma. For the lower photon energy t…

Precision Measurement of the X(3872) Mass in J/psi pi+ pi- Decays

The CDF Collaboration, T. Aaltonen

We present an analysis of the mass of the X(3872) reconstructed via its decay to J/psi pi+ pi- using 2.4 fb^-1 of integrated luminosity from ppbar collisions at sqrt(s) = 1.96 TeV,…

Observation of the Omega_b^- and Measurement of the Properties of the Xi_b^- and Omega_b^-

CDF Collaboration, T. Aaltonen

We report the observation of the bottom, doubly-strange baryon Omega^-_b through the decay chain Omega^-_b -> J/psi Omega^-, where J/psi -> mu^+ mu^-, Omega^- -> Lambda K^-, and La…

Search for the Neutral Current Top Quark Decay t-->Zc Using the Ratio of Z-Boson + 4 Jets to W-Boson + 4 Jets Production

CDF Collaboration, T. Aaltonen

We have used the Collider Detector at Fermilab (CDF II) to search for the flavor-changing neutral-current (FCNC) top quark decay ${t\goes Zc}$ using a technique employing ratios of…

Inclusive production of protons, anti-protons and neutrons in p+p collisions at 158 GeV/c beam momentum

NA49 Collaboration, T. Anticic, B. Baatar +45

New data on the production of protons, anti-protons and neutrons in p+p interactions are presented. The data come from a sample of 4.8 million inelastic events obtained with the NA…

Search for WW and WZ production in lepton plus jets final state at CDF

The CDF Collaboration, T. Aaltonen

We present a search for WW and WZ production in final states that contain a charged lepton (electron or muon) and at least two jets, produced in sqrt(s) = 1.96 TeV ppbar collisions…
