Why are we interested to investigate Ds+ p-p+p+ dynamics?

• Dc = Ds Cabibbo allowed at 2 vertices

• Br(p-p+p+) =(1.4?0.4)% (High)

• In Ds+ p-p+p+ we have

initial state (c,s)

(u,d) final state

Which mechanism could make

the quarks (c,s) to “vanish” ?

The decay Ds+ p-p+p+ is the best candidate to proceed through annihilation

Non Resonant channel
