Packet C: Bonus 10

This particle has a spin of 2 because the stress–energy tensor is second order. For 10 points each:
[10e] Name this hypothetical gauge boson that mediates an attractive fundamental force.
ANSWER: gravitons
[10h] This scientist is the first namesake of a theorem that implies the graviton cannot be a composite particle because it is massless and has spin 2. This physicist also names the soft graviton theorem.
ANSWER: Steven Weinberg [accept Weinberg–Witten theorem; accept Weinberg soft graviton theorem]
[10m] As a consequence of the Weinberg–Witten theorem, a composite spin-2 graviton would violate a covariance condition named for this physicist. By the CPT theorem, any theory with CPT symmetry is invariant under this physicist’s transformations.
ANSWER: Hendrik Lorentz [accept Lorentz transformations; accept Lorentz invariance; accept Lorentz covariance]
