None so far.

## Minor corrections (Unimportant errors in equations)

p. 177, last paragraph. Only rotations by π are antipodal points and only these should be identified. That is, “rotations about an axis by an angle θv are the same as rotations about an axis pointing in the opposite direction by the angle -θv” should be  “rotations about an axis by an angle π are the same as rotations about an axis pointing in the opposite direction by the angle π”.

p. 177, last paragraph. The topology of SO(3) is that of RP3, however, RP3 = S3/Z2 not B3/Z2 as written.

p. 182, problem 10.5a, “infinitesimal spinor” should be simply “spinor”.

p. 240, Eq. (13.117): There should an overall - sign on the right-hand side, as in Eq. (13.108).

p. 240, Eq. (13.118): There should be ¼ multiplying the right-hand side.

p. 271, Eq. (14.97): The first and second indices should be permuted independently. So the sum should be over “permutations {in jn}” and the summand {A_i1 j1 … A_in jn}.

p. 321, Eq. (17.33). The terms in this equation should be appropriate for a complex scalar selectron and smuon. So a number of fields should be barred or conjugated and the factors of ½ should be removed.

p. 347, Eq. (19.52), First line. The exponent of ∆ should be "d/2 - 2" instead of "2 - d/2".

p. 359, Eq. (20.23). There second expression "2(f(Q2) +δ1)σ0" should be  "2Re[f(Q2) +δ1]σ0".

p. 454, Eq. (24.10): The two delta-functions should be inside the integral.

p. 511, Eq. (26.14). The color matrices should be symmetrized. That is "Taik Tbkj" should be replaced by "{Ta,Tb}ij".

p. 635, end of second paragraph. The sentence “Note that for B-L to be non-anomalous, there must be right-handed neutrinos, since these carry lepton number.” should be removed.

## Typos (Superficial formatting issues)

p. 17, beginning of Sectino 2.21. "foce" should be "force".

p. 137, Eq. (8.144), the last term should be "ημν" instead of "ηαβ".

p. 152, 4th line, reference to Section 8.2.3 should be a reference to Section 8.4.2.

p. 201, next to last line of chapter. "the rigorous proof does require a Lagrangian description" should be "the rigorous proof does not require a Lagrangian description".

p. 238, 2 lines below Eq. (13.105), "The 1 comes from radiation polarized in the plane of scattering and the cos2θ from polarization out of the plane" should be  "The 1 comes from radiation polarized out of the plane of scattering and the cos2θ from polarization in the plane".

p. 255, after Eq. (14.7), "where A comes from the product..." should be "where det A comes from the product...".

p. 277, Eq. (14.131), there should be "..." at the end of the first line.

p. 311, last line of first paragraph, "the Bohr radius a0 ∼ m/α" shuold be "the Bohr radius a0 ∼ 1/(mα)".

p. 312, below Eq. (16.65). “Regulate the m=0 singularity” should be “regulate the Q=0 singularity”.

p. 375, Eq. (20.A.87): a "µ" superscript is missing on the final q1 term.

p. 562, Second paragraph “non-casual” should be “non-causal”.

p. 572, below Eq. (28.37). Should be “Fπ = 92 MeV” instead of “Fπ = 130 MeV” .

p. 615, problem 29.7c). “non-relativistic” should be “ultra-relativistic”.

p. 750, 3rd line after Eq. (34.69)" 1010 should be 1010
