Flow and correlation phenomena measurements in pp, pPb and PbPb collisions at CMS
(EPJ Web of Conferences, 2018) [Trabalho apresentado em evento]The quarkgluon plasma created in high energy collisions of large nuclei exhibits strong anisotropic collective behavior as a nearly perfect fluid, flowing with little frictional resistance or viscosity. It has been ... 
Measurements of flow and correlation phenomena in pp, pPb and PbPb collisions at CMS
(Proceedings of Science, 2016) [Trabalho apresentado em evento]Many aspects of anisotropic collective flow in ultra relativistic heavyion collisions have been studied extensively in the past years using two or more particle correlations. An overview of collective flow and particle ... 
Improved effectiverange expansions for small and large values of scattering length
(European Journal of Physics, 2018) [Artigo]The textbook effectiverange expansion of scattering theory is useful in the analysis of lowenergy scattering phenomenology when the scattering length a is much larger than the range R of the scattering potential: a ... 
A formalism for steering with local quantum measurements
(New Journal of Physics, 2018) [Artigo]We develop a unified approach to classical, quantum and postquantum steering. The framework is based on uncharacterised (blackbox) parties performing quantum measurements on their share of a (possibly unphysical) quantum ... 
Natural and dynamical neutrino mass mechanism at the LHC
(Physical Review D, 2018) [Artigo]We generalize the scalar triplet neutrino mass model, the type II seesaw. Our model displays compelling theoretical and experimental features. First, lepton number violation is dynamically generated, without introducing a ... 
Interpolating quantum electrodynamics between instant and front forms
(Physical Review D, 2018) [Artigo]The instant form and the front form of relativistic dynamics proposed by Dirac in 1949 can be linked by an interpolation angle parameter δ spanning between the instant form dynamics (IFD) at δ=0 and the front form dynamics, ... 
Band Structure Engineering by Alloying for Photonics
(Advanced Optical Materials, 2018) [Artigo]Surface plasmon polaritons (SPPs) enable the deep subwavelength confinement of an electromagnetic field, which can be used in optical devices ranging from sensors to nanoscale lasers. However, the limited number of metals ... 
Lagrangian Formulation, Generalizations and Quantization of Null Maxwell's Knots
(Fortschritte der Physik, 2018) [Artigo]Knotted solutions to electromagnetism are investigated as an independent subsector of the theory. We write down a Lagrangian and a Hamiltonian formulation of Bateman's construction for the knotted electromagnetic solutions. ... 
A selfbound matterwave bosonfermion quantum ball
(Laser Physics Letters, 2018) [Artigo]We demonstrate the possibility of creating a selfbound stable threedimensional matterwave spherical bosonfermion quantum ball in the presence of an attractive bosonfermion interaction and a small repulsive threeboson ... 
Equations of motion from Cederwall’s pure spinor superspace actions
(Journal of High Energy Physics, 2018) [Artigo]Using nonminimal pure spinor superspace, Cederwall has constructed BRSTinvariant actions for D = 10 superBornInfeld and D = 11 supergravity which are quartic in the superfields. But since the superfields have explicit ... 
Bounding quantum dark forces
(Physical Review D, 2018) [Artigo]Dark sectors lying beyond the Standard Model and containing subGeV particles which are bilinearly coupled to nucleons would induce quantum forces of the CasimirPolder type in ordinary matter. Such new forces can be tested ... 
Perturbative corrections to technicolor
(Physical Review D, 2018) [Artigo]The full solution of technicolor (TC) SchwingerDyson equations should include radiative corrections induced by extended technicolor (ETC) (or other) interactions. We verify that when TC is embedded into a larger theory ... 
DES science portal: Creating scienceready catalogs
(Astronomy and Computing, 2018) [Artigo]We present a novel approach for creating scienceready catalogs through a software infrastructure developed for the Dark Energy Survey (DES). We integrate the data products released by the DES Data Management and additional ... 
Searching for axionlike particles with proton tagging at the LHC
(Journal of High Energy Physics, 2018) [Artigo]The existence of an axionlike particle (ALP) would induce anomalous scattering of light by light. This process can be probed at the Large Hadron Collider in central exclusive production of photon pairs in protonproton ... 
Influence of the pp Nuclear Interaction on the Rate of the LowEnergy p+Hμ → (pp)α +μ Reaction
(Atoms, 2018) [Artigo]The influence of an additional strong pp nuclear interaction in a threechargeparticle system with arbitrary masses is investigated. Specifically, the system of p, μ, and p is considered in this paper, where p is an ... 
Urban vehicular traffic: Fitting the data with a hybrid stochastic model. Part II
(Physica A: Statistical Mechanics and its Applications, 2018) [Artigo]In this second part of our research we used the models presented in Modeling vehicular traffic networks. Part I (Otero et al., 2018) to perform an analysis of the urban traffic as recorded by cameras distributed in a chosen ... 
Finitesize correction scheme for supercell calculations in Diracpoint twodimensional materials
(Scientific Reports, 2018) [Artigo]Modern electronic structure calculations are predominantly implemented within the super cell representation in which unit cells are periodically arranged in space. Even in the case of noncrystalline materials, defectembedded ... 
Modeling vehicular traffic networks. Part I
(Physica A: Statistical Mechanics and its Applications, 2018) [Artigo]We propose three models for the traffic of vehicles within a network formed by sites (cities, carrental agencies, parking lots, etc.) and connected by twoway arteries (roads, highways), that allow forecasting the vehicular ... 
Vortex lattice in the crossover of a Bose gas from weak coupling to unitarity
(Scientific Reports, 2018) [Artigo]The formation of a regular lattice of quantized vortices in a fluid under rotation is a smokinggun signature of its superfluid nature. Here we study the vortex lattice in a dilute superfluid gas of bosonic atoms at zero ... 
Evolution of complexity following a quantum quench in free field theory
(Journal of High Energy Physics, 2018) [Artigo]Using a recent proposal of circuit complexity in quantum field theories introduced by Jefferson and Myers, we compute the time evolution of the complexity following a smooth mass quench characterized by a time scale δt in ...
