Textbook Problem

(a) Verify from its quark composition that the particle could be an excited state of the proton.

(b) There is a spread of about 100 MeV in the decay energy of the interpreted as uncertainty due to its short lifetime. What is its approximate lifetime?

(c) Does its decay proceed via the strong or weak force?

To determine

(a)

Whether the Δ+ particle could be an exited state of proton.

Explanation

Quark structure of Δ+ particle =uud

Quark structure of proton =uud

Decay of Δ+ particle is given by, Δ+π0+p

To determine

(b)

The uncertainty in short life time of Δ+ particle.

To determine

(c)

Whether the decay of Δ+ particle proceeds via strong or weak force.
