(III) What magnetic field B is needed to keep 998-GeV
protons revolving in a circle of radius 1.0 km? Use the
relativistic mass. The proton's “rest mass" is 0.938 GeV/c².
(1 GeV = 10° eV.) [Hint: In relativity, m,elv²/r = qvB_is
still valid in a magnetic field, where mrel =
Ym.]
(b) A K+ meson composed of a up-quark and a strange-antiquark has the
following major decay modes:
i. K+ → µtvµ
ii. K+ + 7°e+e
iii. K+ + n+0
iv. K+ → n+°7°
Draw a Feynman diagram for cach of these decays and indicate whether these
procced via the clectromagnetic, strong or weak interaction, or a combination
thereof?
(c) Pions are also produced in the upper atmosphere. [In fact, the sequence is proton
(from outer space) hits proton (in atmosphere) -> p +p+pions.
+
The pions then decay into muons: ñ→µ¯¯ +vµ; π†→µ* +vµ.] But the lifetime of the
pion is much shorter, a hundredth that of the muon. Should the pions reach ground
level? (Assume that the pions also have a speed of 0.998 c.)

- *39 Will the universe continue to expand forever? To attack this question, assume that the theory of dark energy is in error and that the recessional speed v of a galaxy a distance r from us is determined only by the gravitational interaction of the matter that lies inside a sphere of radius r centered on us. If the total mass inside this sphere is M, the escape speed v, from the sphere is v. = V2GMIT (Eq. 13-28).
