Abstract
The conversion of protons to positrons at the horizon of a black hole (BH) is considered. It is shown that the process may efficiently proceed for BHs with masses in the range \( \sim {{10}^{{18}}}\)–\({{10}^{{21}}}\) g. It is argued that the electric charge of BH acquired by the proton accretion to BH could create electric field near BH horizon close to the critical Schwinger one. It leads to efficient electron-positron pair production, when electrons are back captured by the BH while positrons are emitted into outer space. Annihilation of these positrons with electrons in the interstellar medium may at least partially explain the origin of the observed 511 keV line.
黑洞将质子转化为正电子
摘要 研究了质子在黑洞（BH）视界处向正电子的转换。研究表明，对于质量在 \( \sim {{10}^{18}}}\)-\({{10}^{21}}}) g 范围内的黑洞，这一过程可以有效地进行。这将导致高效的电子-正电子对产生，当电子被 BH 重新俘获时，正电子将被发射到外层空间。这些正电子与星际介质中的电子湮灭，至少可以部分解释观测到的 511 keV 线的起源。
