In this paper, we perform a comprehensive analysis of the high-energy data of the recent bright short GRB 200415A, which was located close to the Sculptor galaxy. Our results suggest that a magnetar giant flare provides the most natural explanation for most observational properties of GRB 200415A, including its location, temporal and spectral features, energy, statistical correlations, and high-energy emissions. On the other hand, the compact star merger GRB model is found to have difficulty reproducing such an event in a nearby distance. Future detections and follow-up observations of similar events are essential to firmly establish the connection between SGR giant flares and a subsample of nearby short GRBs.   The baryo-quarkonium picture for hidden-charm and bottom pentaquarks and LHCb P-c(4380) and P-c(4450) states 期刊论文  OAI收割 PHYSICS LETTERS B, 2019, 卷号: 789, 页码: 562-567 作者:  Ferretti, J;  Santopinto, E;  Anwar, MN;  Bedolla, MA   |  收藏  |  浏览/下载：76/0  |  提交时间：2019/07/19 SHORT-DISTANCE ANALYSIS  HADRONIC TRANSITIONS  HEAVY QUARKS  J/PSI  SYSTEMS  MESON   Nucleon resonances with hidden charm in gamma p reactions 期刊论文  OAI收割 PHYSICAL REVIEW C, 2019, 卷号: 100, 期号: 3, 页码: 35206 作者:  Wu, Jia-Jun;  Lee, T-S H.;  Zou, Bing-Song   |  收藏  |  浏览/下载：28/0  |  提交时间：2020/06/16 SHORT-DISTANCE ANALYSIS  HEAVY-QUARK SYSTEMS  PENTAQUARK STATES  PHOTOPRODUCTION  SCATTERING  MESON  DECAY   eta(c)- and J/psi-isoscalar meson bound states in the hadro-charmonium picture 期刊论文  OAI收割 PHYSICS LETTERS B, 2018, 卷号: 782, 页码: 702-706 作者:  Ferretti, J   |  收藏  |  浏览/下载：117/0  |  提交时间：2018/12/27 SHORT-DISTANCE ANALYSIS  HEAVY-QUARK SYSTEMS  TRIANGLE SINGULARITIES  PSI SPECTROSCOPY  QCD VACUUM  TRANSITIONS  MODEL  CHROMODYNAMICS  X(3872)  NUCLEI   Diffractive photoproduction of eta(c) 期刊论文  OAI收割 NUCLEAR PHYSICS A, 2003, 卷号: 727, 期号: 40972, 页码: 333-352 作者:  Ma, JP;  Ma, JP , Acad Sinica, Inst Theoret Phys, POB 2735, Beijing 100080, Peoples R China.   |  收藏  |  浏览/下载：16/0  |  提交时间：2012/08/30 Short-distance Analysis  Effective Field-theory  Pp Elastic-scattering  Heavy-quark Systems  Quantum Chromodynamics  Parton Distributions  Hadronic Transitions  Meson Production  Exclusive Decay  2 Pions
