论文摘要
Bañados，Silk和West（BSW）已显示出质量能量的中心（E_CM）从Infinity的静止开始，并在Schwarzschild Black Hole的地平线附近碰撞总是有限的。在这种交流中，我们将BSW场景和研究两个粒子在静态球形对称黑洞的地平线附近碰撞。令人惊讶的是，我们发现，即使对于静态的球形对称（即Schwarzschild类似）黑洞，也可以从黑洞的地平线附近的两个测试粒子中获得任意高的E CM，如果一个微调地测量运动的参数。
It has been shown by Bañados, Silk and West (BSW) that the center of mass energy (E_cm) of test particles starting from rest at infinity and colliding near the horizon of a Schwarzschild black hole is always finite. In this communication, we extent the BSW scenario and study two particles with different energies colliding near the horizon of a static spherically symmetric black hole. Surprisingly, we find that even for the static spherically symmetric (i.e., Schwarzschild like) black holes it is possible to obtain an arbitrarily high E cm from the two test particles colliding near the horizon of a black hole, if one fine-tunes the parameters of geodesic motion.
