Doubly Heavy Tetraquark Resonant States
Qi Meng, Masayasu Harada, Emiko Hiyama +2
Spectrum of the doubly heavy tetraquarks, , is studied in a constituent quark model. Four-body problem is solved in a variational method where the real scaling tech…
Classifying near-threshold enhancement using deep neural network
Denny Lane B. Sombillo, Yoichi Ikeda, Toru Sato +1
One of the main issues in hadron spectroscopy is to identify the origin of threshold or near-threshold enhancement. Prior to our study, there is no straightforward way of distingui…
Unveiling the pole structure of S-matrix using deep learning
Denny Lane B. Sombillo, Yoichi Ikeda, Toru Sato +1
Particle scattering is a powerful tool to unveil the nature of various subatomic phenomena. The key quantity is the scattering amplitude whose analytic structure carries the inform…
Model independent analysis of coupled-channel scattering: a deep learning approach
Denny Lane B. Sombillo, Yoichi Ikeda, Toru Sato +1
We develop a robust method to extract the pole configuration of a given partial-wave amplitude. In our approach, a deep neural network is constructed where the statistical errors o…
Decay properties of Roper resonance in the holographic QCD
Daisuke Fujii, Atsushi Hosaka
We investigate the one pion decay of the Roper resonance in the Sakai-Sugimoto model of the holographic QCD. The nucleon and Roper resonance emerge as ground…
Relativistic corrections to decays of heavy baryons in the quark model
Ahmad Jafar Arifi, Daiki Suenaga, Atsushi Hosaka
We investigate relativistic corrections of order , where is the constituent quark mass, to heavy baryon decays by emitting one pseudoscalar meson in the quark model. T…
