Samuel Beckett and the Writers of Port-Royal
No full textIt has been observed that ‘the literary influences on Beckett have been far more important than has been acknowledged, and more important indeed, than the philosophical influences’ (Smith 2002: 3). The truth of this statement is evidenced by the description that scholars have given of Samuel Beckett’s relationship to seventeenth century French classicism. To date, critical interest has been limited for the most part to the figure of the philosopher René Descartes on the (fragile) grounds that Beckett was exclusively concerned with the Cartesian imperative of clarity and order, the fundamental dualism between body and mind, and Nominalism.
Together with the assumption that Beckett’s vision was essentially Cartesian, his literary filiation with Pascal was suggested by critics, but only in terms of Beckett’s formal approach to the theatre. In his short article on En attendant Godot in 1953, the playwright Jean Anouilh was among the first reviewers to suggest that Beckett’s drama synthesizes the encounter between ‘classicism’ and a ‘modern’ form of art. It is well known that Beckett retained a lifelong admiration for Pascal – indeed, Pascal was one of his ‘old chestnuts’ (Knowlson 1997: 653). Little attention has been paid, however, to the originality of Pascal’s thought, the specific nature of his prose, and the impact these might have had upon Beckett’s mature work, especially the trilogy and the subsequent short prose. Yet, in the literary and philosophical context of post-war France, Beckett’s filiation with Pascal, their corresponding preoccupations, were evident to his contemporaries, who identified Pascal as an underlying presence in his works
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
A model-independent Dalitz plot analysis of B±→DK± with D→K0Sh+h− (h=π,K) decays and constraints on the CKM angle γ
No full textA binned Dalitz plot analysis of B ±→DK ± decays, with D→KS0π+π- and D→KS0K+K-, is performed to measure the CP-violating observables x ± and y ± which are sensitive to the CKM angle γ. The analysis exploits 1.0 fb -1 of data collected by the LHCb experiment. The study makes no model-based assumption on the variation of the strong phase of the D decay amplitude over the Dalitz plot, but uses measurements of this quantity from CLEO-c as input. The values of the parameters are found to be x -=(0.0±4.3±1.5±0.6)×10 -2, y -=(2.7±5.2±0.8±2.3)×10 -2, x +=(-10.3±4.5±1.8±1.4)×10 -2 and y +=(-0.9±3.7±0.8±3.0)×10 -2. The first, second, and third uncertainties are the statistical, the experimental systematic, and the error associated with the precision of the strong-phase parameters measured at CLEO-c, respectively. These results correspond to γ=(44-38+43)°, with a second solution at γ→γ+180°, and r B=0.07±0.04, where r B is the ratio between the suppressed and favoured B decay amplitudes
Measurement of the D+/- production asymmetry in 7 TeV pp collisions
No full textThe asymmetry in the production cross-section \sigma of D+/- mesons, A_P = (\sigma(D+) - \sigma(D-))/(\sigma(D+) + \sigma(D-)), is measured in bins of pseudorapidity \eta and transverse momentum p_T within the acceptance of the LHCb detector. The result is obtained with a sample of D+ -> K_S pi+ decays corresponding to an integrated luminosity of 1.0 fb^-1, collected in pp collisions at a centre of mass energy of 7 TeV at the Large Hadron Collider. When integrated over the kinematic range 2.0 K_S pi+ decay is negligible. No significant dependence on \eta or p_T is observed
Measurement of the time-dependent CP asymmetry in B0 -> J/ψ KS0 decays
No full textThis Letter reports a measurement of the CP violation observables SJ/ψK0S and CJ/ψK0S in the decay channel B0→J/ψK0S performed with 1.0 fb−1 of pp collisions at s√=7 TeV collected by the LHCb experiment. The fit to the data yields SJ/ψK0S=0.73±0.07(stat)±0.04(syst) and CJ/ψK0S=0.03±0.09(stat)±0.01(syst). Both values are consistent with the current world averages and within
expectations from the Standard Model

This CP eigenstate mode could be used to measure mixing-induced CP violation in the system. Using a fit to the π+π− mass spectrum with interfering resonances gives . In the interval ±90 MeV around 980 MeV, corresponding to approximately two full f0 widths we also find , where in both cases the uncertainties are statistical and systematic, respectively
Pascal DeAngelis to Albert Britt, June 13, 1919
No full textIn a letter to Albert Britt on June 13, 1919, Pascal DeAngelis announces the release of the newest .22 caliber rim-fire rifle. He informs Britt this project involved seven years of work and consultation with rifle experts, such as Captain T. K. Lee, Captain C. L. Gilman, Lieutenant Colonel Townsend Whelen. Mr. DeAngelis recommends Horace Kephart view and describe this rifle for a review in “Outing” since he is one of the most well-known gun experts. He asks Britt for Kephart’s address to send him the rifle.(Copy.)

UTICA, NEW YORK. U.S.A.
June 13, 1919.
Mr. Albert Britt, Editor,
Outing Publishing Company,
1*1-145 West 36th Street,
New York City.
Dear Sir:
Replying to your courteous letter of the 4th inst., we are about
to announce the appearance of the most seriously designed .22
caliber rim-fire repeating rifle that has ever been manufactured.
The rifle is the result of seven years experimental work in the
factory, guided and checked by suggestions and criticisms from
the ablest and most highly respected firearms,authorities of the
country. We have had the close co-operation and assistance of
Captain T. K. Lee, formerly of the Corps of Rifle Demonstrators,
Ordnance Department, USA, who has been international small-bore
champion for many years, and is unquestionably the finest smallbore shooter in the world. Captain C. L. Gilman, USA- former
Secretary of the Western League of the N.R.A., Lieut. Col.
Townsend Whelen, USA, author of the book "American Rifles'* and
the highest military firearms authority in the country,
Lieut. Col. D. C. McDougall, USMC, Major J. J. Dooley, USMC,
Major H. L. Smith, USMC, Major W. D. Smith, USMC, and others too
numerous to mention.
We should be delighted to submit one of these rifles to the writer's
old friend, Mr. Horace Kephart, for critical review to be published
in OUTING. Mr. Kephart is one of the highest firearms authorities
in the world, and easily ranks with the men mentioned above. We
feel that it is a decided honor both to the Savage Arms Corporation
to have the rifle criticised and reviewed by Mr. Kephart, and to
Outing to have a man of Mr. Kephart's distinction as a contributor.
We should very much prefer, however, not to have this rifle or any
other arm of our manufacture criticised editorially by a man of
markedly less ability, experience and reputation, whose favorable
criticism would carry no weight with the well informed shooting
public, and whose unfavorable criticism would be of no value in
producing any suggestions or changes, or any modifications which
would not be desirable.
In other words, we would be delighted to have anything we make
submitted to Mr. Kephart, knowing that his criticism would be fair
and impartial, based on the widest experience and knowledge of his
subject, and entitled to the greatest respect. We should not have
the temerity to suggest any change or modification in any criticism
that Mr. Kephart should write, no matter how unfavorable it might be
to our own product. If our arms have weak points, we have no right
to have fair criticism "soft pedaled," but we would dislike to
submit a firearm for editorial criticism to anyone whose standing
or ability does not entitle him to recognition as an authority.
If you will be good enough to give us Mr. Kephart's address, we
would be glad to ship the rifle to him for critical review.
Very truly yours, T**^%±3&L«**r
