标题： Black Holes from Colliding Wavepackets

摘要： 高能粒子碰撞中黑洞形成的论据基于两个碰撞的Aichelburg-Sexl解的经典几何中出现封闭陷阱表面。 然而，最近的分析表明，在这个似是而非的视界上曲率和量子涨落很大，这可能使半经典分析无效。 我们表明，这个问题是不现实的经典点粒子极限的产物：对于由量子波包描述的粒子，或对于连续物质分布，陷阱表面确实在受控范围内形成。 显示英文摘要

摘要： Arguments for black hole formation in collisions of high-energy particles have rested on the emergence of a closed trapped surface in the classical geometry of two colliding Aichelburg-Sexl solutions. Recent analysis has, however, shown that curvatures and quantum fluctuations are large on this apparent horizon, potentially invalidating a semiclassical analysis. We show that this problem is an artifact of the unphysical classical point-particle limit: for a particle described by a quantum wavepacket, or for a continuous matter distribution, trapped surfaces indeed form in a controlled regime.
