Deviations of the leptonic branching ratios of the heavy Higgs in the MSSM with broken R-parity
(2018)
We performed a phenomenological study of the leptonic decay modes of a heavy Higgs in a supersymmetric scenario which we called the ϵλ-MSSM, in which we added ϵ-bilinear and λ-trilinear terms to break R-parity explicitly, ...
Preparação e caracterização de nanocápsulas peptídicas destinadas à veiculação de compostos terapêuticos

Study on the relationship between wall shear stress and aspect ratio of cerebral aneurysms with different pressure differences using cfd simulations
(World Scientific Publishing Co. Pte Ltd, 2018)
CFD simulations were performed for 60 human cerebral aneurysms (30 previously ruptured
and 30 previously unruptured) to study the behavior of the time-averaged wall shear stress
(TAWSS) with respect to the aspect ratio ...
Measurement of the relative branching ratio BR(Ξc+→p+K−π+)/BR(Ξc+→Ξ−π+π+)
(2001)
We report the observation of the Cabibbo suppressed decay Ξc+→pK−π+ using data collected with the FOCUS spectrometer during the 1996–1997 Fermilab fixed target run. We find a Ξc+ signal peak of 202±35 events. We have ...
Production of the Y(4260) state in B meson decay
(2015-05-14)
We calculate the branching ratio for the production of the meson Y(4260) in the decay B<sup>-</sup>→Y(4260)K<sup>-</sup>. We use QCD sum rules approach and we consider the Y(4260) to be a mixture between charmonium and ...
Production of the y (4260) State in B Meson Decay
(2016-05-06)
We calculate the branching ratio for the production of the meson Y(4260) in the decay B- → Y(4260)K- . We use QCD sum rules approach and we consider the Y(4260) to be a mixture between charmonium and exotic tetraquark, ...
NMR study of branched polyethylenes obtained with combined Fe and Zr catalysts
(2002)
The products obtained with the system {[(ArN=C(Me))2C5H3N]FeCl2}/MAO (Ar = 2-C6H4(Et)) (1) and the ones obtained by the use of 1 in conjunction with Me2SiInd2ZrCl2/MAO (2) or EtInd2ZrCl2/MAO (3) were completely characterized ...
Chemical abundance analysis of red giant branch stars in the globular cluster E3
(2018)
Context. Globular clusters are known to host multiple stellar populations, which are a signature of their formation process. The globular cluster E3 is one of the few low-mass globulars that is thought not to host multiple ...
The chemical composition of red giants in 47 Tucanae II. Magnesium isotopes and pollution scenarios
(EDP SCIENCES S A, 2016)
Context. The phenomenon of multiple populations in globular clusters is still far from understood, with several proposed mechanisms to explain the observed behaviour. The study of elemental and isotopic abundance patterns ...
