超新星冷却对轻隐扇形规范玻色子的限制

Constraints on Light Hidden Sector Gauge Bosons from Supernova Cooling

James B. Dent, Francesc Ferrer, Lawrence M. Krauss

摘要:

我们推导出新的边界上隐藏的扇区规范玻色子,可以产生新的能量损失机制,在超新星,扩大排除区域的质量耦合空间的一个重要因素相比,早期的估计。在确定这种边界时,需要考虑这些粒子的俘获和可能的衰变,就像中子和质子的散射一样。对于饱和电流边界区域附近的质量和耦合,由于宇宙历史上所有超新星的累积效应,也可能产生这种规范玻色子的重要背景。

英文摘要:

We derive new bounds on hidden sector gauge bosons which could produce new energy loss mechanisms in supernovae, enlarging the excluded region in mass-coupling space by a significant factor compared to earlier estimates. Both considerations of trapping and possible decay of these particles need to be incorporated when determining such bounds, as does scattering on both neutrons and protons. For masses and couplings near the region which saturates current bounds, a significant background of such gauge bosons may also be produced due to the cumulative effects of all supernovae over cosmic history.
