Amistat i pensament entre Georges Bataille i Maurice Blanchot: fites de l'itinerari vital i intel·lectual de Bataille prèvies a l'encontre amb Blanchot
(Universitat Ramon Llull. Càtedra Ramon Llull Blanquerna, 2017)
Georges Bataille i Maurice Blanchot es conegueren personalment a principis de la dècada de 1940. L’amistat que establiren fou per a ambdós escriptors un estímul intel·lectual profund, que deixà empremta ...
Measurement of the C P Asymmetry in B + → K + μ + μ − Decays
(American Physical Society, 2013-10)
A measurement of the CP asymmetry in Bþ ! Kþ þ decays is presented using pp collision data,
corresponding to an integrated luminosity of 1:0 fb 1, recorded by the LHCb experiment during 2011 at ...
Observation of CP violation in B ± → D K ± decays
(Elsevier, 2012-06-06)
An analysis of B+ to DK+ and B+ to Dpi+ decays is presented where the D meson is reconstructed in the two-body final states: K+pi-, K+K-, pi+pi- and pi+K-. Using 1.0 fb-1 of LHCb data, measurements of ...
Precise measurements of the properties of the B1(5721)0,+ and B *2 (5747)0,+ states and observation of B+,0π−,+ mass structures
(Springer, 2015-04-07)
Invariant mass distributions of B+π− and B0π+ combinations are investigated in order to study excited B mesons. The analysis is based on a data sample corresponding to 3.0 fb−1 of pp collision data, ...
Observation of the suppressed ADS modes B± → [π± K∓ π+ π−] DK± and B± → [π± K∓ π+ π−] Dπ
(Elsevier, 2013-06-10)
An analysis of B±→DK±B±→DK± and B±→Dπ±B±→Dπ± decays is presented where the D meson is reconstructed in the four-body final state K±π∓π+π−K±π∓π+π−. Using LHCb data corresponding to an integrated luminosity ...
Measurement of the isospin asymmetry inB→K(∗)μ+μ−decays
(Springer, 2012-07-20)
The isospin asymmetries of B → K (∗) μ + μ − decays and the partial branching fractions of B 0 → K 0 μ + μ − and B + → K ∗+ μ + μ − are measured as a function of the di-muon mass squared q 2 using an ...
First evidence for the annihilation decay mode B+→D+sφ
(Springer, 2013-02-07)
Evidence for the hadronic annihilation decay mode B+→D+sϕ
is found with greater than 3σ significance. The branching fraction and CP asymmetry are measured to be
$
B(B+→D+sϕ)=(1.87+1.25−0.73(stat)±0.1 ...
Maurice Blanchot y el judaísmo
(Universitat Ramon Llull. Facultat de Filosofia, 2015)
Este artículo pretende estudiar los lazos entre la obra crítica de Maurice Blanchot (1907-2003) y el judaísmo. Con este objetivo, repasa la cuestión de su prematuro antisemitismo, la fascinación por lo ...
Precision luminosity measurements at LHCb
(IOPscience, 2014-12)
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy √
s. In this paper results are reported from the luminosity
calibrations carried out ...
Observation of B0s –B¯¯¯¯0s mixing and measurement of mixing frequencies using semileptonic B decays
(Springer, 2013-12-04)
The B0s and B 0 mixing frequencies, Δm s and Δm d , are measured using a data sample corresponding to an integrated luminosity of 1.0 fb−1 collected by the LHCb experiment in pp collisions at a centre ...
