Observation of a New Particle in the Search for the Standard Model Higgs Boson with the ATLAS Detector at the LHC
2012 · paper · Physics
Reports a search for the Standard Model Higgs boson with the ATLAS detector, combining proton-collision data at 7 and 8 TeV. It finds a new neutral boson with mass about 126 GeV, at 5.9 standard deviations, compatible with the Higgs boson.

Reference or label Section 6.3 says the signal theoretical uncertainties "are de-scribed in Section 9", but they are described in Section 8 (item 6, 'Theory uncertainties'); Section 9 is 'Results'.

- p. 15 Section 6.3, first paragraph
These are de-scribed in Section 9.
- p. 7 Section 4.3
The theoretical uncertainties associated with the sig-nal are described in detail in Section 8.
Judge's note: On p15 the image reads 'These are de-scribed in Section 9.' In the text, Section 8 'Correlated systematic uncertainties' (p17) item 6 gives the QCD-scale, PDF and branching-ratio uncertainties on the signal. Section 9 is 'Results', and a search of it found no discussion of signal theory uncertainties. The parallel pointers in Sections 4.3 and 5.6, and the introduction's outline, all point to Section 8.

10 minor (typos and the like; most checked by the judge only)
Wording Table 1 caption says "“PYTHIA” indicates that PYTHIA6 and PYTHIA8 are used for simulations of √s = 7 TeV and √s = 8 TeV data, respectively", but the text below says PYTHIA6 is used "for 7 TeV samples and 8 TeV samples produced with MadGraph [70, 71] or AcerMC"; the table rows "AcerMC [61]+PYTHIA" and "MadGraph+PYTHIA" carry no exception marker.
- p. 4 Table 1 caption
“PYTHIA” indicates that PYTHIA6 and PYTHIA8 are
- p. 4 Section 3, paragraph after Table 1
PYTHIA6 [69] (for 7 TeV samples and 8 TeV sam-ples produced with MadGraph [70, 71] or AcerMC)
- p. 4 Table 1, rows tqb, WZ and Wγ*
AcerMC [61]+PYTHIA
Judge's note: Checked on the page 4 image. The caption states the rule without qualification, and the paragraph directly under the table gives an exception for MadGraph and AcerMC 8 TeV samples, which are exactly the rows labelled +PYTHIA (tqb, WZ, Wγ*). The text does supply the correct information, so this is an unqualified caption, not a wrong fact; a reader of the caption alone would assume PYTHIA8 for those 8 TeV samples.

Typo Section 4.3: "has been found to be negligible ." has a stray space before the full stop.
- p. 7 Section 4.3, right column
has been found to be negligible .
- p. 7 Sec. 4.3
found to be negligible .
Judge's note: Visible on the page 7 image, right column: a clear gap between 'negligible' and the full stop. Not an extraction artefact.

Typo Section 4.3: "served for m4l > 160 GeV" uses a plain italic l in the subscript where the running text elsewhere uses m4ℓ.
- p. 7 Section 4.3, right column
served for m4l > 160 GeV
Judge's note: Page 7 image: the subscript in 'm4l > 160 GeV' is a plain italic l, while the same column and the left column print m4ℓ with the script ℓ (for example 'm4ℓ = 600 GeV', and the Figure 2 caption). Notation inconsistency in body text, cosmetic only.

Typo Table 4 caption: "is also given for the 8 TeVdata" is missing a space between 'TeV' and 'data'.

Typo Typo on p16, Section 6.3: "initial state an final state radiation" should read "initial state and final state radiation".

initial state an final state
- p. 16
initial state an final state radiation
Judge's note: The page image shows 'an final state', so this is not an extraction artefact.

Judge's note: Page 20 image: the right-hand edge of Figure 9 carries labels 0σ, 1σ, 2σ, 3σ, 4σ, 5σ, 6σ, each on a dashed horizontal line; the caption says 1 to 6 σ. The 0σ line (p0 = 0.5) is a trivial reference, so nothing is misread; the caption simply omits it.

Only the authors can say what is right here.
Judge's note: Rests on outside knowledge: whether the cited JHEP article's own title uses 'lHC'. The image of p23 shows 'Higgs production at the lHC'. Other references in the same list, such as [33] and [34], use 'LHC'. This is cosmetic, and only the authors can say whether it copies the original title.

Typo Reference [99] reads "OPAL Collaboration Collaboration, K. Ackerstaff et al."; the word 'Collaboration' is duplicated.
- p. 24 Reference [99]
OPAL Collaboration Collaboration
Judge's note: Crop C040-a shows the duplicated word on the page. Other collaboration entries (e.g. [96]-[98] 'ATLAS Collaboration') have the word once. Evident fix: 'OPAL Collaboration'.

Typo Reference [140] gives the journal as "Dokl. Akad. Nawk. USSR 60 (1948) 207"; 'Nawk.' appears to be a misspelling of 'Nauk'.
- p. 25 Reference [140]
Nawk. USSR 60 (1948) 207
Only the authors can say what is right here.
Judge's note: Rests on outside knowledge: the journal's name is Doklady Akademii Nauk SSSR, so the abbreviation should read 'Nauk'. Crop C041-a confirms the page prints 'Nawk.' (also with the bold face applied to 'USSR 60' rather than the volume alone). Cosmetic.

Judge's note: Rests on outside knowledge: Sun Yat-sen University is located in Guangzhou, and 'Guangzhou' is the standard spelling. The image of p38 shows 'Guanzhou'.
