A hydrogen target is bombarded by pions. Calculate the threshold values of kinetic energies of these poins making possible the following reactions: (a) pi^(-)+prarr K^(+)+Sigma^(-), (b)pi^(0)+prarr K^(+)^^ ^(0) |

Answer» Solution :(a) Here `T_(th)=((m_(k)+m_(Sigma))^(2)-(m_(x)+m_(p))^(2))/(2m_(p))C^(2)` SUBSTITUTION GIVES `T_(th)=0.904GeV` (b) `T_(th)=((m_(k)^(+)+m_(^^))^(2)-(m_(PI^(0))m_(p))^(2))/(2m_(p))c^(2)` Substitution gives `T_(th)= 0.77GeV` |
