Abstract

The recently observed very high energy (VHE) photons dubbed as GRB221009A by several terrestrial observatories such as LHAASO and Carpet-2 require a physics explanation beyond the standard model. Such energetic gamma ray bursts, originating from yet unknown very distance source at redshift z = 0.1505, would be directly scattered by extragalactic background lights (EBL) rendering its improbable detection at the earth. We show that dark photon which resides in extra dimension would be able to resolve this issue when it oscillates resonantly with the photon in similar fashion with neutrino oscillation. We demonstrate that, for dark photon mass equals to 1 eV, the probability of GRB221009A photons with energy above 0.2 TeV to reach the earth lies in the range between

10^{- 6} to 95 %

for kinetic mixing values

10^{- 14} \leq ϵ \leq 10^{- 12.5}

GRB221009A通过额外维度的暗光子-光子共振转换

最近观测到的高能光子（VHE）被几个地面观测站（如LHAASO和Carpet-2）命名为GRB221009A，需要一个超越标准模型的物理学解释。这种能量充沛的伽马射线爆发，起源于红移z = 0.1505的未知极远源，将被河外背景光（EBL）直接散射，使其在地球上不太可能被探测到。我们表明，当暗光子以类似中微子振荡的方式与光子共振时，驻留在额外维度的暗光子将能够解决这一问题。我们证明，当暗光子质量等于1 eV时，能量大于0.2 TeV的GRB221009A光子到达地球的概率在电流约束允许的动力学混合值10−14≤λ≤10−12.5之间，介于10−60 ~ 95%之间。
