The authors propose a detector for the Collider which will cover the largest possible ranges of angles with electromagnetic calorimetry and charged tracking, and with hadronic calorimetry for the forward direction. The goal for the complete detector would be acceptance down to approx 1 mrad, in contrast to CDF and D0, which have coverage only to approx. 40 mrad. Because of the limitations of physical space and running time in all but B0 and D0, such a detector will have to be very compact and compatible with a variety of difficult boundary conditions. For this reason, they propose to run a test program at F0 during the second of the present Collider running period, utilizing existing calorimeters and tracking systems. A less desirable option which can be installed at E0 is also described. With luck there may be the possibility of physics from the test program as well. The final version of the detector would be installed at E0 after the main Injector upgrade. the detector is designed to study processes with relatively large cross sections. The running time requirements are thus minimal and data taking would require running a small fraction of the time with the electrostatic separators turnedmore » off.« less

The old idea that the photon is a Goldstone boson emergent from a spontaneously broken theory of interacting fermions is revisited. It is conjectured that the gauge-potential condensate has a vacuum expectation value which is very large, perhaps the GUT/Planck momentum scale, but that the magnitude of the effective potential which generates it is very small, so small that in the limit of vanishing cosmological constant it would vanish. In this way, the threat of unacceptably large observable, noncovariant residual effects is mitigated. The linkage of these ideas to other speculative ideas involving black holes and parametrizations of Standard-Model coupling constants is also described.

Our intent is to make simple-minded mass estimates of the baryons containing charm and strange quarks.
