§ 1.3: Add at the bottom of page 9, after “observed.” — The exotic $J^{PC} = 1^{-+}$ states π1(1400) and π1(1600) are now established, and considered candidates for $q\bar{q}g$ hybrids. See the brief discussion in §4 of C. Amsler, “non-$q\bar{q}$ mesons,” in the 2006 Review of Particle Physics. For a discussion of the many recently reported multiquark meson candidates, many of which have exotic non-$q\bar{q}$ quantum numbers, see S. L. Olsen, “$XYZ$ Meson Spectroscopy,”  arXiv:1511.01589.

Add at the end of the first complete sentence on page 10 — Reported evidence for light $qqqq\bar{q}$ “pentaquark” states has not been sustained. For a perspective on the searches, see K. H. Hicks, “On the Conundrum of the Pentaquark,” Eur. Phys. J. H 37, 1 (2012). Evidence for heavy pentaquarks, though with nonexotic $N^*$ quantum numbers, was reported by R. Aaij et al. (LHCb Collaboration), “Observation of $J\!/\!\psi p$ Resonances Consistent with Pentaquark States in $\Lambda^0_b \to J\!/\!\psi K^- p$ Decays,” Phys. Rev. Lett. 115, 072001 (2015).

New editions:

A second edition (2014) of Dynamics of the Standard Model, by Donoghue, Golowich, and Holstein, cited on pages 24, 89, 94, and 183, has been published by Cambridge University Press.

Corrections:

Equation (2.3.4): On the far right-hand side, $\delta_\mu$ should read $\partial_\mu$.

Equation (6.1.71): The first equation should read $q_1 \cdot p_1 = mE$, not $me$. Noted by Kaushik Roy.

Equation (6.5.6): The middle expression is lacking a factor $\left(1 - 4m_f^2/M_H^2\right)^{1/2}$. Thanks to Boris Kayser!

Equations (6.5.8) and (6.5.9): The factors of $x$ resp. $x^\prime$ in the denominators are spurious. The rates for a heavy Higgs boson into a pair of intermediate vector bosons should read $\begin{array}{rclcr}{{\Gamma(H \rightarrow W^+ W^-)}} & = & \displaystyle{\frac{G_{\mathrm{F}} M_H^3} {32\pi\sqrt{2}}}{(1-x)^{1/2}} (3x^2 - 4x+4) , & \qquad & (6.5.8) \\[18pt]{\Gamma(H \rightarrow Z^0 Z^0)} & = & \displaystyle{\frac{G_{\mathrm{F}} M_H^3} {64\pi\sqrt{2}}}{(1-x^\prime)^{1/2}} (3x^{\prime 2} - 4x^\prime +4) ,& \qquad & (6.5.9)\end{array}$

where $x = 4M_W^2/M_H^2$ and $x^\prime = 4M_Z^2/M_H^2 = x/\cos^2 \theta_{\mathrm{W}}$. Thanks to Matthew Low for noticing!

Equation (7.4.70): The factor $E^\prime E$ on the right-hand side should read ${\displaystyle\frac{E^\prime}{E}}\,$. Thanks to Ken Lane for noticing!

Equation (B.1.4): The denominator should contain $m_\alpha^3$, not $m_\alpha^2$, so that
$\displaystyle{\frac{d\Gamma_{\beta\alpha}}{d\Omega_{\rm{cm}}}} =\displaystyle{\frac{|{\cal{M}}_{\beta\alpha}|^2}{64\pi^2}}\displaystyle{\frac{{\cal{S}}_{12}}{m_\alpha^3}} \cdot S. \qquad\mathrm{(B.1.4)}$

Thanks to Lukas Pritchett for noticing!
