Abstract
A high speed and highly radiation-resistant barium fluoride crystal array is under development by the Caltech group in collaboration with the Brookhaven National Lab, the Shanghai Institute of Ceramics in China, the KEK in Japan and the AccSys Technology Inc. in California. The barium fluoride array will serve as a prototype for a high precision electromagnetic calorimeter at the SSC, which has a unique capability in detecting the Higgs particles in the mass region between 80 to 180 GeV. The research and development program involves 3 aspects: (1) production of barium fluoride crystals with very large size (800 cm3) and high radiation resistance (10 MRads); (2) development of a fast readout system with an optical and electrical suppression on the slow component; and (3) development of an effective precision calibration system based on radiative capture of a pulsed proton beam from an Radio Frequency Quadruploe accelerator on a calcium fluoride target.
Representing the team of H. Newman (Caltech), H. Ma, C. Woody (BNL), Z.Y. Wei, Z.W. Yin (SIC, China), T. Matsuda, F. Takasaki (KEK, Japan) and R. Hamm (AccSys , California).

The cross-section of H0 →γγ is scaled up by a factor of two according to J. Stirling, a talk given in a recent “ECFA-LHC meeting” at CERN. An argument was given that one should use a running b quark mass (in the spirit of perturbative QCD) in evaluating the H0 → bb̄ coupling. Since the b quark mass is smaller than the scale of the Higgs mass, the width for this channel is reduced by almost a factor of two. Also other quark channels are reduced by the same argument. Since the effective width into γγ is unchanged, the actual branching ratio thus is increased. According to T. Sjostrand, this increase will be implemented into the PYTHIA program in near future.
