Charge Conjugation and Parity Violations as a Signature for Black Hole Formation or Other New Physics in Hadron Collisions

I point out that there have been essentially no tests of discrete symmetries, such as baryon number, charge conjugation (C), parity (P), strangeness, isospin, etc., in high energy, high pT hadron collisions. If, for example, black hole formation (BHF) occurs, we might expect large violations of C, P, >... I propose new tests of C and P that can be adapted to a variety of new physics scenarios by selecting events with appropriate topologies. Large effects, such as ~10% longitudinal polarizations of outgoing particles, might be expected in events involving BHF. These tests may provide more sensitive searches for new physics at existing colliders

A forward detector for the DO area at Fermilab

About 90% of the energy from a √s=2000 GeV p̄p collision goes out at angles <2° in the laboratory. We propose a detector for the DO area which emphasizes tracking and calorimetry down to the smallest practical angles. A detector of this type is essential for studying the general features of collisions at Collider energies, particularly the energy flow, multiplicity and inelastic cross section. It will also play a very important role in selecting hard collisions which will reduce the background for new physics in a central detector.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/87579/2/318_1.pd
