The quark combination needed to produce a meson.
Answer to Problem 40P
Solution:
The quark combination needed to produce meson is .
Explanation of Solution
All quarks have spin and an electric charge of either or . Antiquarks have opposite sign of electric charge , baryon number , strangeness , charm , bottom , and top .
To produce a meson, the total charge on the quark combination must be zero. Also the value of the baryon number is , and the value of strangeness must be but the value of charm must be as per condition. So, there must be a c quark with a charge of . To neutral a meson, there must be another quark with a charge of . So, the second quark must be an antiquark. The only combination with those properties is an anti-up quark. Hence required combination of the quark is .
