The Assumptions:
(and a rating 1-10 of how realistic I find them, 10 being relistic)

1)The general form of a fock state wave function in the momentum fraction representation for and eigen state of gross quark number with n quarks:

Psi(x₁,...x_n) = A/(m_p² -sum_i=1,n[m_t²_i/x_i])

A is a normalization constant, x_i is the fraction of the hadron's longitudinal momentum carried by quark i in the infinite momentum frame, m_t²=m²+k_t² and k_t is the transverse momentum of the parton. The entire denominator here is called the off mass shell variable. I have a hard time seeing why. (6)

2) The binding energy of the quarks has no effect on the diffraction process. That is, a hadron in a higher Fock state can be detected as multiple hadrons without some binding energy changing the momentum components of the detected particles durring dissociation. (7)

3) The average transverse momentum of a given quark is proportional to it's (effective) mass. The effective masses are taken to be m_q=(1/3)*m_p=313MeV, m_s=500MeV, m_c=1500MeV and the constant of proportionality is one for light quarks (including strange) and for charm it's 2/3. (6 Try putting in 2/3 for all quarks)

4) The probability for a diffractive process to occur is eaqual to the probability for a fusion process to occur. (1)

5) For a given fock state i, the probability of diffractively producing a certain charmed (anticharmed) hadron h, given that a diffractive process will occur, is a_i^h/b_i where a_i^h refferes to how many of the b_i hadrons that can be diffractively produced from fock state i are identical to h. This follows from the assumption that each quark has the same quantity of color charge and is therefore bound witth he same quantity of energy as every other quark. However, it seems to me like the more quarks in the final diffractively produced hadron the less likely it is to be produced. I can see, however, that my objection is not valid untill there are more than 5 quarks in the initial state.(7)

6) Eeach of the 10 charmed hadrons (with no heavy quarks ther than the c, ie D+, Ds+, D0, lambda c, sigma c ++, sigma c +, sigma c 0, Xi c +, Xi c 0, Omega c) are produced with equal probability in fusion processes. Seems to me like more massive hadrons should be produced less often, but the QCD factorization theorem disagrees with my intuition. (3)
