“ There is a crack in everything; that’s how the
light gets in. ” —Leonard Cohen
Notation: “p.n” = page n,
“P.n” = paragraph n,
“l.n” = line n,
“S.m.n” = section n of chapter m;
n > 0 is counted downward/forward,
n < 0 upward/backward.
If you notice any kind of error in the book, please, do let me know!
p.73, Digression 2.7, l. –4: “ relation
” → “ relations ” (plural)
p.74, (2.65): insert a missing ℏ on the right-hand side of the inequality
p.99, l. 1 after (3.58): “ p2=...
” → “ p'2=...”
p.99, (3.60): “ ..., pi ), where...
” → “ ..., p'i ), where...”
p.144, l.–1; p.560, l.2: “
Saharov ” → “ Sakharov ” (Western-standard
spelling)
p.183, (5.80a): “
1/4 εμνρσ... ” → “
1/8 εμνρσ... ”
p.225, (6.6e):
“...= – (... ” →
“ ...= – c (both locations)
&
“...ℏc... ” →
“ ...ℏ... (both denominators);
p.247, l.3 after (6.85): “
momentum ” → “ moment ” (left-most
word-fragment, and middle of the row)
p.325, Digression 9.2: the results are given in the un-normalized
basis, (no summation) eμ = eμ/hμ
and eμ = eμhμwhere,
(hμ)2 = gμμ ,
where eμ
= eμ are the usual unit-vectors;
see again in Appendix B.2.
p.329, l.1 under
Eq. (9.45) and subsequently: “
energy-momentum tensor density ” → “
energy-momentum density tensor ”
(the quantity defined in
Eq. (9.45) is a tensor—not a tensor density as defined in
Definition B.2 on p.522; its components however are
densities in the other sense of the word: they are “some quantity
per unit spatial 3D-volume”)
p.340, Digression 9.5., l.3 after (9.73b): “
10−127 ” → “ 10−123 ” and “ 83 ”
→ “ 79 ”
p.342, (9.81), anti de Sitter branch: Whereas a “flat slicing”
analogue of the de Sitter branch can be obtained, this most certainly is not it.
Instead, suffice it here to cite the standard global expression “
− c2 f(r) dt2
+ dr2/ f(r) + dr2dΩ2
with f(r) = 1 + |ΛAdS|r2/3 ”,
and recall that ΛAdS<0
p.365, l.6–7: “ Dmytro ”
→ “ Dmitry ”
p.467, Eq. (A.40o): “
J±J∓” → “
J∓J± ”
p.503, Eq. (B.13): multiply the right-hand side in both rows by n!
p.514, Def. B.6, l.2: “
(p'q') ” → “ (p',
q') ” (pair-separating comma)
p.518, Eq. (B.80c), the 2nd relative sign (multiplying the
3rd term): “ – ”
→ “ + ”
p.526, Table C.2, units of ϵ0 : “ ... m–2 ”
→ “ ... m–3 ”

information science”
Frequently Asked Questions:
« What is the one key distinction of this book, as compared with other texts on elementary particle physics?
» Conceptually consistent comprehensiveness. Most other elementary particle physics texts aim to reach the contents of the Standard Model, which describes “subatomic physics.” This text also introduces grand unified models, general relativity and cosmology, supersymmetry and superstrings while following the same conceptually unified methodology. Borrowing from the introduction (p.xiii) and the concluding chapter (p.409):
« Could elementary particles be minuscule black holes?
» Yes... unverifyably so and for an imperceptibly short time: As discussed in Digression 9.5, the Schwarzschild radius (of the event horizon) of an electron evaluates to 1.353×10–57m and its charge horizon comes out to be 9.152×10–37m — both of which are smaller than the Planck length. Furthermore, the Hawking evaporation time of an electron-mass black hole evaluates to 6.355×10–107s. Indeed, quite unobservable and for an even more imperceptibly short time.
So, if elementary particles were black holes, the only stable spin-½ particles in the Standard Model would be: the u-quarks (lightest fractionally charged), electrons (lighter still, but integrally charged) and electron-neutrinos (lightest and chargeless). The s, c, b, t-quarks would have to evaporate; even d-quarks could not be stable (akin to the neutron in stable nuclei), since their evaporation is 60 orders of magnitude faster than Planck time, leaving no chance for the molasses-slow (10–23s is 12 orders of magnitude slower than Planck time) strong interactions to stabilize it.
