Problem

The

\Xi^0

baryon has quark content

uss

. ((a)) Compute its charge

Q

(in units of

e

), baryon number

B

and strangeness

S

by summing over the three quarks. ((b)) State the two totals allowed when three spin-

1/2

quarks are combined, and say which of these two is the measured ground-state spin of the

\Xi^0

(mass

1314.9\,\mathrm{MeV}/c^2

), given that it belongs to the same spin family as the proton and neutron.
