From at least the time of Thomas Edison, U.S. engineers have used the word “bug” to refer to flaws in the systems they developed. This short word conveniently covered a multitude of possible problems. It also suggested that difficulties were small and could be easily corrected. IBM engineers who installed the ASSC Mark I at Harvard University in 1944 taught the phrase to the staff there. Grace ...

Recent results from the Mark II Detector at SPEAR are presented. These include measurements of the decays r--to-vr and T-+K*-(890)~,, observation of direct photons at the $, inclusive proton and A production and measurements of charmed baryon and charmed meson decays.

Hadronic decays of the w’ are reviewed and a new preliminary upper limit of B(~‘+pn )<7.0~10-~ at 90% C.L. from the Mark III is presented. T he I,V’ is the 23S, cc quark-antiquark vector meson and is the only well established radial excitation. The hadronic decay rate of the w’ relative to the J/v should scale as the . ratio of the three gluon widths which are proportional to the leptonic width...
