Z-boson production in p-Pb collisions at √sNN = 8.16 TeV and Pb-Pb collisions at √sNN = 5.02 TeV
(2020) [Artigo de periódico]Measurement of Z-boson production in p-Pb collisions at √sNN = 8.16 TeV and Pb-Pb collisions at √sNN = 5.02 TeV is reported. It is performed in the dimuon decay channel, through the detection of muons with pseudorapidity ... -
Zero-inflated-censored Weibull and gamma regression models to estimate wild boar population dispersal distance
(2021) [Artigo de periódico]The dynamics of the wild boar population has become a pressing issue not only for ecological purposes, but also for agricultural and livestock production. The data related to the wild boar dispersal distance can have a ... -
Zig-zag networks of self-excited periodic oscillations in a tunnel diode and a fiber-ring laser
(2013) [Artigo de periódico]We report numerical evidence showing that periodic oscillations can produce unexpected andwide-ranging zigzag parameter networks embedded in chaos in the control space of nonlinear systems. Such networks interconnect ... -
Zircon U-Pb geochronology, Sm-Nd and Pb-Pb isotope systematics of Ediacaran post-collisional high-silica Acampamento Velho volcanism at the Tupanci area, NW of the Sul-Rio-Grandense Shield, Brazil
(2017) [Artigo de periódico]We present new U-Pb zircon ages and Sm-Nd-Pb isotopic data for volcanic and hypabyssal acid rocks from the northernmost exposure of the Acampamento Velho Formation in the NW portion of the Sul-Rio-Grandense Shield, Brazil. ... -
Zooming into local active galactic nuclei : the power of combining SDSS-IV MaNGA with higher resolution integral field unit observations
(2017) [Artigo de periódico]Ionized gas outflows driven by active galactic nuclei (AGN) are ubiquitous in high-luminosity AGN with outflow speeds apparently correlated with the total bolometric luminosity of the AGN. This empirical relation and ... -
Αβ-crystallin and laminin-332 are prognostic markers for triple negative breast cancers in a brazilian series
(2019) [Artigo de periódico]Purpose: Association between increased αβ-crystallin (ABC) and abnormal LN332 (LN332) expression in triple negative (TNBC) and basal-like (BLBC) breast cancers has been suggested recently. This study aims to evaluate ABC ... -
Λ+c production and baryon-to-meson ratios in pp and p-Pb collisions at √sNN=5.02 TeV at the LHC
(2021) [Artigo de periódico]The prompt production of the charm baryon Λ+c and the Λ+c/D0 production ratios were measured at midrapidity with the ALICE detector in pp and p-Pb collisions at √sNN=5.02 TeV. These new measurements show a clear decrease ... -
Λc+ production in Pb–Pb collisions at √sNN=5.02 TeV
(2019) [Artigo de periódico]A measurement of the production of prompt Λc+baryons in Pb–Pb collisions at TeV with the ALICE detector at the LHC is reported. The Λc+ and Λ-c- were reconstructed at midrapidity (|y|<0.5) via the hadronic decay channel ... -

(2018) [Artigo de periódico]An invariant differential cross section measurement of inclusive π0 and η meson production atmid-rapidity in pp collisions at √ s = 8 TeV was carried out by the ALICE experiment at the LHC. The spectra of π0 and η mesons ... -
Σ (1385)± resonance production in Pb–Pb collisions at √sNN = 5.02 TeV
(2023) [Artigo de periódico]Hadronic resonances are used to probe the hadron gas produced in the late stage of heavy-ion collisions since they decay on the same timescale, of the order of 1–10 fm/c, as the decoupling time of the system. In the hadron ... -
ϒ production and nuclear modification at forward rapidity in Pb–Pb collisions at √sNN=5.02 TeV
