# Second Printing Corrections

This page lists corrections to the second printing (June 2014).
The printing is listed in the middle of the imprints page (e.g. First published 2014/2nd printing 2014). If your book has any of the errata listed on this page, it is the second (or first) printing.

## Important corrections (Errors in derivations or results)

In the electron self-energy graph in QED in dimensional regularization, some order ε terms were left out. The first relevant equation is Eq. (18.12) on p. 327. Correction as follows:

Reads in second printing:

This affects the dimensional-regularization on-shell counterterms:
p. 333, Eqs. (18.51) and (18.52): The “5/2” should be a “2” in both equations.p. 343, Eq. (19.25): The “5/2” should be a “2”.
It also affects Eq. (18.50) on p. 333:

the first line of Eq. (18.60) on p. 335:

and Eq. (18.62) also on p.335:

Finally, the pole-to-msbar conversion is affected.
p. 336, Eq. (18.65): The “5” should be a “4”.
p. 337, Eq. (18.70): The “5” should be a “4”.
p. 412, Eq. (22.57): The “5” should be a “4”.

Similar factors were not included in the the vertex correction graph in Chapter 19.
p. 347, Eq. (19.50): Correction as follows:

Reads in second printing:

p. 347, Eq. (19.52): On the first line, the factor of “(2-4/d)“ should be a factor of “(d-2)2/d” in two places and on the second line, the “-1” should be “-2”.
p. 347, Eq. (19.54): The “-½” should be a “-1”.
p. 348, Eq. (19.55): The “-½” should be a “-1” on the first line, and the “5/2” should be a “2” on the second line.
p. 348, Eq. (19.56): The “5/2” should be a “2”.

pp. 628-631. There are a number of minor corrections in Section 30.3: the transformations of ψ and its conjugate may be unrelated; the one-particle Hilbert space should be introduced first in Eq. (30.58) rather than Eq. (30.62); the Jacobian is not singular but rather it is undefined. Rather than list all the corrections separately, this PDF contains the full update of Section 30.3.
Only Eqs. (30.57) to (30.60), the discussion around these equations, and an overall sign in Eq. (30.66) are changed.

## Minor corrections (Unimportant errors in equations)

p. 80, Eq.(7.9): There should be no “hbar” in this equation. The hbar cancels because <0|T {φ0 (x)φ0 (y)}|0> = hbar DF (x, y).

p. 85, below Eq. (7.33): The “V(t)” on the right hand side should be “V(t0)”. That is, this inline equation should be “VI (t) = exp[ i H0(t-t0)] V(t0) exp[- i H0(t-t0)]”.
p. 88, 4th line, 6th line and Eq. (7.53): The factor of “i H0(t- t0)” in the exponent should be “ - i H0(t- t0)” in all 3 instances.
p. 89: Eqs. (7.61): Both exponentials should be surrounded by a time-ordering operator.
p. 90, Eq. (7.68): On the last line of this, the factor of “2” should be a “3”.
p. 97, Eq. (7.90): First “ϕ” should be “ϕ0”.
p. 99, Eq. (7.106): “M” should be “i M” on the left-hand side.
p. 101, Eq. (7.A.113): All the “ϕ”’s in this equation in should be “ϕ0”’s.

p. 117: Eq. (8.29): Momentum should have a down index: “pμ=(E,0,0,pz)” should be “pμ=(E,0,0,pz)”
p. 124, Eq. (8.69): The second polarization vector should be “ε2” not “ε1”.
p. 126, Eq. (8.78): The second polarization vector should be “ε2” not “ε1”.
p. 185, Eq. (11.2): The sign in front of the F. σ term should be “-”, as in Eq. (11.1).
p. 188 Eq. (11.13): The sign in the exponent should be -. That is “e ip x” should be “e-i p x”.

p. 190, Eq. (11.26): up2 and vp2 are incorrect. Correction as follows:

Reads in second printing:
p. 234: Eq. (13.79): “e 4” should be “α4”.
p. 235: Eq. (13.80): A factor of “p4” is missing from the denominator in the final term. That is, “64 π4 … “ should be “64 π4 p4… “
p. 248, Eq. (13.164): The “8π” in the denominator should be “16π”.
p. 261, Eq. (14.41): The time-ordering symbol is missing on the on left-hand side.
p. 271, Eqs. (14.96), (14.97), (14.98) and (14.100) on p. 272, the ordering of the θ’s should be reversed (but not the θ-bar’s). Equivalently, the measure can be written with each θ-bar proceeding each θ. That is, these measures should read:

 Reads in second printing: One correct form Another correct form:
p. 283, 5th line of Section 14.8.4: “m = (b-n)/2” should be “ m = (n-b)/2”.
p. 292, Eq. (15.25): The third form of this term is wrong (the others are correct). The denominator should be “eε - 1” instead of “1- e - ε ”.

p. 564, Eq. (28.9): “ωp” should be “ωq”.
p. 564, 1st line below Eq. (28.9), “δ3(p − k)” should be “δ3(q − p)”.
p. 568, Eq. (28.23): The quartic term is ambiguous. A more precise Lagrangian has the traces explicit, as:

p. 578, First line: “For R > ξ, the type-I …” should be “For ξ > R, the type-I …”.
p. 605, Eq. (29.81): “s” and “d” are reversed in the last parenthesis on the second line.
p. 617, Eq. (30.1): In the second term on the right hand side, the “ϕ” should be a “π“.

## Typos (Superficial formatting issues)
