论文摘要
我们研究了轻度互动的光线颗粒的太阳发射，足以自我向热。所得的流出的行为就像流体，在其自身的热压下加速到太阳系中的相对论散装速度。与普通的非交互情况相比，本地流出至少具有$ \ sim 10^3 $更高的数字密度，并且相应地至少$ \ sim 10^3 $每个粒子的平均能量降低。我们展示了这种通用现象是如何在一个黑暗扇区中产生的，该黑暗区域由毫米粒子组成，通过黑暗光子强烈自我互动。在该模型中出现的毫米级等离子体风具有新颖但可预测的特征，可以鼓励新的实验方向。这种现象证明了如何远离最简单模型的一小步会导致根本不同的结果，从而激发了对黑暗扇区颗粒的更广泛搜索。
We study the solar emission of light dark sector particles that self-interact strongly enough to self-thermalize. The resulting outflow behaves like a fluid which accelerates under its own thermal pressure to highly relativistic bulk velocities in the solar system. Compared to the ordinary non-interacting scenario, the local outflow has at least $\sim 10^3$ higher number density and correspondingly at least $\sim 10^3$ lower average energy per particle. We show how this generic phenomenon arises in a dark sector comprised of millicharged particles strongly self-interacting via a dark photon. The millicharged plasma wind emerging in this model has novel yet predictive signatures that encourages new experimental directions. This phenomenon demonstrates how a small step away from the simplest models can lead to radically different outcomes and thus motivates a broader search for dark sector particles.
