17 Eq. (2.4) The quantity (1-v2) should not be an overall factor. It should multiply only the elements of the first two rows. Ambika Prasad Panigrahi, Berhampur University
18 Eq. (2.9) The quantity (1-u2) should not be an overall factor. It should multiply only the elements of the first two rows. Ambika Prasad Panigrahi, Berhampur University
106 Eq. (4.204) In the fraction that appears in the argument of the delta function, the term s2 should be simply s, in gothic script. In the denominator, the quantity s should also be in gothic font, implying that it is the Mandelstam variable. Christian Farina, University of Pittsburgh
122 Eq. (5.40) In the denominator of the right side, the Mandelstam variable appears, so it should be s in gothic font. Christian Farina, University of Pittsburgh
128 Eq. (5.67) The symbol k should not be boldfaced, i.e., we imply the 4-vector k1

309 Argument for Eq. (11.62) Eq. (11.62) can be obtained directly from Eq. (11.59), using Eq. (11.54). No need to invoke Eq. (11.60).  
310 Argument for Eq. (11.63) The argument is partly circular here. It is easier to calculate the normalization constant first. For this, note that there is always an SU(2) subgroup of any SU(N) for N>2. The fundamental of SU(N) decomposes under the SU(2) subgroup as a doublet and N−2 singlets. Taking Kronecker product of N and N* representations, we then obtain

3 + (2N − 4) doublets + (singlets)

of SU(2). The normalization constant of the adjoint of SU(N) is the sum of the normalization constants of these SU(2) representations, i.e., C(ad) = 2 + ½(2N − 4) = N. Then Eq. (11.59) can be used to obtain Eq. (11.63).

 
330–332 Eq (12.37) onwards All references to the Casimir invariant C2 should be changed to the normalization constant C defined in Eq (11.39, p 305). The reason for the occurrence of this constant has been described correctly in the last sentence starting on page 331, but the constant has been wrongly referred to as the Casimir invariant throughout §12.2.3.
389 Eq. (13.26) There should be an integral sign before the d3p factors on the right side of the equation. Roopam Sinha, Saha Institute
392 Eq. (13.37), 2nd line, denominator (2π3) (2π)3
397 Eq. (13.61), 1st line The argument of the delta function should be x'p + q − p' instead of xp + q − p' Roopam Sinha, Saha Institute
398 Eq. (13.63), right side 2Q2α2 Q2α2 Roopam Sinha, Saha Institute
403 Eq. (13.82) The crescented 's' in the denominator of the expression in the middle (i.e., the one between two equality signs) will have a square. Roopam Sinha, Saha Institute
416 Eq. (14.14) The second equation in this line should have Q in place of Q+. Christian Farina, University of Pittsburgh
467 Eq. (16.30)
where cI is 2 for complex multiplets and 1 for real multiplets.
Anirban Kundu, Calcutta University
478 Eq. (16.63) A factor of Zμ is missing on the right side. Tarak Nath Maity, IIT Kharagpur
