Observation of X(3872) production in pp collisions at s√=7~TeV
(Springer, 2012-05-04)
Using 34.7 pb−1 of data collected with the LHCb detector, the inclusive production of the X(3872) meson in pp collisions at s√=7~TeV
is observed for the first time. Candidates are selected in the ...
Study of NVIS Channel for USN Protocol Definition in Antarctica
(MDPI, 2020-06)
Every year, the number of ubiquitous sensor networks (USN) is increasing and the need for remote USN communications is emerging in some scenarios. As an alternative to satellite communications, more ...
Measurement of charged particle multiplicities and densities in pp collisions at s√=7TeV in the forward region
(Springer, 2014-05-24)
Charged particle multiplicities are studied in proton–proton collisions in the forward region at a centre-of-mass energy of s√=7TeV with data collected by the LHCb detector. The forward spectrometer ...
Measurement of the ¯B0s→D−sD+s and ¯B0s→D−D+s Effective Lifetimes
(American Physical Society, 2014-03-19)
The first measurement of the effective lifetime of the ¯B0s meson in the decay ¯B0s→D−sD+s is reported using a proton-proton collision data set, corresponding to an integrated luminosity of 3 fb−1, ...
Measurement of CP violation in B0→ D∗±D∓ decays
(Springer, 2020-02)
The decay-time-dependent CP asymmetry in B0→ D∗±D∓ decays is mea- sured using a data set corresponding to an integrated luminosity of 9 fb−1 recorded by the LHCb detector in proton-proton collisions at ...
La ausencia como categoría teológica. Michel de Certeau, bajo el signo de la ruptura
(Facultat de Teologia de Catalunya, 2013-12)
The historian, anthropologist and sociologist Michel de Certeau (1925-1986) compiled a historiographic map of social practices based on the concept of the “présence manquante”. In this article, the main ...
Measurement of the lifetime of the Bc+ meson using the Bc+→ J/ψπ+ decay mode
(Elsevier, 2015-03-06)
The difference in total widths between the Bc+ and B+mesons is measured using a data sample corresponding to an integrated luminosity of 3.0 fb-1collected by the LHCb experiment in 7 and 8 TeV centre-of-mass ...
