Does asymptopia being at 5 GeV/c in πN scattering?

  • Published:
Lettere al Nuovo Cimento (1971-1985)

Conclusion

  1. i)

    The simple formula σ+ = σ/4q2 describes the total cross-section data at (4/60) GeV/c with, a remarkable accuracy.

  2. ii)

    If this formula is inserted into the forward dispersion relation for all momenta above 4 GeV/c, one obtains a prediction for the real part in agreement with the data.

  3. iii)

    It would be useful to reconsider critically the arguments, which led to the expectation that an important contribution to πN scattering comes from f- or P’-exchange, where αP’(0) ≈ 0.5.

  4. iv)

    The tail of the Coulomb interference term in dσ-/dt - dσ+/dt could be larger than expected.
