Abstract
Now, are hard collisions really all that easy? To be sure, calculation (not to mention measurement) of hard-collision processes is far from simple, and I mean no disrespect by the title. It is meant in the physicists’ sense that “what is possible to do is easy; the impossible is merely hard.”

I believe that in modern language this inconsistency has to do with the presence of vacuum-to-vacuum bubbles in the evolution matrix U(t), but I am not sure on this point. Infinite renormalization constants also complicate the issue.
Actually, a better estimate is E/Am2, where Am2 = m2 - m2 is the mass (squared) splitting between the pion and tfie next important massive state x. I thank M. Strikman for this comment.

G. Farrar, Phys. Rev. Letters 56, 1643(1986).The theoretical argument for banning polarization measurements is expressed in this paper: the full amplitude is A = C + D where C, the clean amplitude, is computable and D, the dirty amplitude, is not. D in magnitude is 30% of C so it only affects unpolarized data at the 10% level. Polarization data dependent on the interference term is dirty even though asymmetries up to 60% are possible.
See for example S. Brodsky and G. DeTeramond, SLAC preprint SLACPUB-4504, Dec, 1987.
Internal-target data from Fermilab show backward protons (xF - 0.8±0.1) about 7% polarized at pi, = 500 MeV; this polarization disappears at pT = 1 GeV. But what about higher pT? And what about pp -( n + x? See M. Corcoran et. al., Phys. Rev. D22, 2624(1980).

For color singlet initial-state partons, the existence of a rapidity gap is very credible; an example is W+W -( H° as discussed by Y. Dokshitzer, V. Khose, and S.
