英文摘要	We calculate the diffuse high energy (TeV-PeV) neutrino emission from hyperflares of soft-gamma repeaters (SGRs), like the hyperflare risen from SGR 1806-20 on December 27 of 2004, within the framework of the fireball model. The fireball model for gamma-ray bursts (GRBs) can explain well the main features of this hyperflare and the subsequent multi-frequency afterglow emission. The expected rate similar to 20-100 GpC(-3) day(-1), of such hyperflares is well in excess of the GRBs rate. Our result shows that the contribution to the diffuse TeV-PeV neutrino background from such hyperflares is less than 10% of the contribution from GRBs. We also discuss the high energy cosmic rays (CRs) from these sources. (C) 2009 Elsevier B.V. All rights reserved.
