  • Correções em next-to-leading order em regras de soma da QCD

    Leal Junior, Jesuel Marques (Universidade Estadual Paulista (UNESP), 2019) [Dissertação de mestrado]
    O método de regras de soma na QCD é um método não-perturbativo em QCD que permite obter observáveis hadrônicos a partir de quantidades universais da QCD, como as massas dos quarks e condensados. Ao longo dos cálculos desse ...
  • Machine learning quantum error correction codes: learning the toric code

    Rodriguez Fernandez, Carlos Gustavo (Universidade Estadual Paulista (UNESP), 2018) [Dissertação de mestrado]
    Usamos métodos de aprendizagem supervisionada para estudar a decodificação de erros em códigos tóricos de diferentes tamanhos. Estudamos múltiplos modelos de erro, e obtemos figuras da eficácia de decodificação como uma função ...
  • Hierarquias integráveis supersimétricas

    Lobo, Gabriel Vieira (Universidade Estadual Paulista (UNESP), 2018) [Dissertação de mestrado]
    Estudamos hierarquias integráveis. Essas hierarquias possuem infinitas equações de movimento que emergem de uma mesma estrutura algébrica. Algumas equações são conhecidas como mKdV e Sinh-Gordon, estas equações possuem ...

    Padula, Sandra S. Autor UNESP (EPJ Web of Conferences, 2018) [Trabalho apresentado em evento]
    The quark-gluon 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

    Padula, Sandra S. Autor UNESP (Proceedings of Science, 2016) [Trabalho apresentado em evento]
    Many aspects of anisotropic collective flow in ultra relativistic heavy-ion collisions have been studied extensively in the past years using two or more particle correlations. An overview of collective flow and particle ...
  • Improved effective-range expansions for small and large values of scattering length

    Adhikari, S. K. Autor UNESP (European Journal of Physics, 2018) [Artigo]
    The textbook effective-range expansion of scattering theory is useful in the analysis of low-energy 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

    Sainz, A. B.; Aolita, L. Autor UNESP; Piani, M.; Hoban, M. J.; Skrzypczyk, P. (New Journal of Physics, 2018) [Artigo]
    We develop a unified approach to classical, quantum and post-quantum steering. The framework is based on uncharacterised (black-box) parties performing quantum measurements on their share of a (possibly unphysical) quantum ...
  • Natural and dynamical neutrino mass mechanism at the LHC

    Gehrlein, Julia; Gonçalves, Dorival; Machado, Pedro A. N.; Perez-Gonzalez, Yuber F. Autor UNESP (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

    Ji, Chueng-Ryong; Li, Ziyue; Ma, Bailing; Suzuki, Alfredo Takashi Autor UNESP (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

    Gong, Chen; Kaplan, Alan; Benson, Zackery A.; Baker, David R.; McClure, Joshua P.; Rocha, Alexandre R. Autor UNESP; Leite, Marina S. (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

    Nastase, Horatiu Autor UNESP; Sonnenschein, Jacob (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 self-bound matter-wave boson-fermion quantum ball

    Adhikari, S. K. Autor UNESP (Laser Physics Letters, 2018) [Artigo]
    We demonstrate the possibility of creating a self-bound stable three-dimensional matter-wave spherical boson-fermion quantum ball in the presence of an attractive boson-fermion interaction and a small repulsive three-boson ...
  • Equations of motion from Cederwall’s pure spinor superspace actions

    Berkovits, Nathan Autor UNESP; Guillen, Max Autor UNESP (Journal of High Energy Physics, 2018) [Artigo]
    Using non-minimal pure spinor superspace, Cederwall has constructed BRST-invariant actions for D = 10 super-Born-Infeld and D = 11 supergravity which are quartic in the superfields. But since the superfields have explicit ...
  • Bounding quantum dark forces

    Brax, Philippe; Fichet, Sylvain Autor UNESP; Pignol, Guillaume (Physical Review D, 2018) [Artigo]
    Dark sectors lying beyond the Standard Model and containing sub-GeV particles which are bilinearly coupled to nucleons would induce quantum forces of the Casimir-Polder type in ordinary matter. Such new forces can be tested ...

    Aguilar, A. C.; Doff, A. Autor UNESP; Natale, A. A. Autor UNESP (Physical Review D, 2018) [Artigo]
    The full solution of technicolor (TC) Schwinger-Dyson equations should include radiative corrections induced by extended technicolor (ETC) (or other) interactions. We verify that when TC is embedded into a larger theory ...

    We present a novel approach for creating science-ready 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 axion-like particles with proton tagging at the LHC

    Baldenegro, C.; Fichet, S. Autor UNESP; von Gersdorff, G.; Royon, C. (Journal of High Energy Physics, 2018) [Artigo]
    The existence of an axion-like 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 proton-proton ...
