baryon has quark content

udc

. ((a)) Compute its charge

Q

, baryon number

B

and strangeness

S

by summing over the three quarks. ((b)) State whether its ground-state spin is

1/2

3/2

, given that it is measured to have mass

2286.5\,\mathrm{MeV}/c^2

and belongs to the lighter of the two spin families available to three spin-

1/2

quarks.
