Momentum-Transfer Dependence in Reactions of the Type $A + p \to Δ^{+ +} + A + π$

We have examined the momentum-transfer distributions in the reactions (1)

π^{+} + p \to Δ^{+ +} (1236) + π^{+} + π^{-}

at a

π^{+}

beam momentum of 7

\frac{GeV}{c}

, and (2)

K^{+} + p \to Δ^{+ +} (1236) + K^{+} + π^{-}

at an incident

K^{+}

momentum of 12.7

\frac{GeV}{c}

. In both instances the

t

dependence (proton to

Δ

) can be represented remarkably well by the simple form

{(t + μ^{2})}^{- 2}

, where

μ^{2} \approx m_{π}^{2}
