A systematic lifting of exchange-degeneracy that clarifies the relationship between pomeron, reggeons and SU3-symmetry violation

Abstract The cylinder correction to the planar S matrix splits I = 0 from I = 1, lifts exchange degeneracy of I = 0 states and induces deviations from ideal mixing. All three effects are approximately described by one parameter which gives the shift of the ω intercept below the ϱ, the couplings of f, f′, ω, ф, the shift of the f above the ϱ, and its tendency to become an SU3 singlet heretofore labeled at t = 0 as the pomeron.

Hadron bootstrap: triumph or frustration?

Physicists usually perceive their disciplines goal as the reduction of nature to fundamentals, and the high‐energy arena has correspondingly been dominated by the search for “basic building blocks.” Finding the quark is for the moment regarded by many as the ultimate prospective triumph; failure to find some such fundamental entity is equated with frustration. There exists, nonetheless, a 180‐degree inverted point of view, which envisions the absence of fundamentals as the ultimate triumph; this is the bootstrap attitude.

Multiperipheral model suggestion of a damped oscillatory component in high energy total cross sections

Abstract We use a simplified multiperipheral model to illustrate the possibility of complex Regge poles that contribute damped oscillations to the total cross section. The model suggests a relation between the period of the oscillations and the rate of growth of average multiplicity with energy.

Prediction of double-pomeron cross sections from single-diffraction measurements

Abstract A particular case of a Mueller formula describing the absence of long-range two-particle correlations is used to predict double-pomeron cross sections from available data on single-diffraction dissociation. Although success of the formula in this application would immediately verify the double-pomeron hypothesis, the converse is not true because the formula may be invalidated by prominent low-energy resonances (such as the f 0 ) in the pomeron-pomeron total cross section. Low-statistics experiments at s = 200 and 400 GeV 2 are in order of magnitude agreement with the formula.

Complex Regge poles and the sign of the two-Pomeranchon discontinuity

Abstract The threshold increase of the two-fireball cross section, with one fireball of large mass and one of small is discussed in terms of complex Regge poles and the sign of the two-Pomeranchon discontinuity. It is shown that even though the cut in the complete amplitude is positive, an approximate Regge representation without complex poles, suitable for a limited energy region, may contain a negative cut. A connection is made between the triple Pomeranchon coupling and the amplitude of the cross-section oscillation associated with the complex poles.

Asymptotic oscillation hypothesis

The observed persistence of threshold effects into the Regge asymptotic region of single-particle inclusive cross sections can be accommodated in a natural fashion by complex Regge poles which, if factorizable, will produce asymptotic damped oscillations in a wide variety of other observable quantities. It is shown that a single pair of such poles, the imaginary part of whose position in the complex J plane is of the order plus or minus 1, can qualitatively explain various anomalies that have been observed in high-energy phenomena. Predictions are made for future measurements. (auth)

A topological theory of electric charge

Abstract A recently-proposed topological theory of strong interactions is extended to electromagnetism. The values of the electric charges of both hadrons and leptons emerge naturally.
