Question

Find the charge, baryon number, strangeness, charm, and bottomness of the J/Ψ particle from its quark composition.

a) Q=0,B=0,S=0,C=1,B′=0
b) Q=1,B=1,S=0,C=0,B′=0
c) Q=0,B=1,S=1,C=0,B′=0
d) Q=0,B=0,S=0,C=0,B′=1

Answer 1

The J/Ψ particle has a net charge of 0, a baryon number of 0, strangeness and charm of 0, and bottomness of 0. The D+ meson has a charge of +1, baryon number of 0, strangeness of 0, charm of +1, and bottomness of 0. The B¯ meson has a charge of -1, baryon number of 0, and bottomness of -1.

Step-by-step explanation:

Properties of J/Ψ Particle and Other Mesons

The J/Ψ particle is composed of a charm quark (c) and an anticharm quark (č). Based on its quark composition, it has a charge (Q) of 0, a baryon number (B) of 0, strangeness (S) of 0, charm (C) of +1 and -1 from the quark and antiquark respectively resulting in 0 net charm, and bottomness (B′) of 0.

For the D+ meson, which has a charm quark (c) and an antidown quark (ăd), the properties are: charge (Q) of +1, baryon number (B) of 0, strangeness (S) of 0, charm (C) of +1, and bottomness (B′) of 0.

The B¯ meson is composed of a bottom quark (b) and an up antiquark (ău), leading to a charge (Q) of -1, a baryon number (B) of 0, strangeness (S) of 0, charm (C) of 0, and bottomness (B′) of -1.

These calculations depend on the intrinsic properties of quarks, such as their electric charge and specific quantum numbers associated with the strong interaction.
