论文摘要
Facet是一个提议的新的子宫理，用于CMS在高光度LHC处的非常向前的方向上搜索深色光子，深色希格斯，沉重的中性瘦素和轴突状颗粒等门户网站。这样的颗粒可以渗透高达50 m的铁，然后在14 m $^3 $真空管中腐烂，这是通过将LHC管的长度长18 m的长度放大到50 cm的半径。
FACET is a proposed new subsysem for CMS to search for portals such as dark photons, dark higgs, heavy neutral leptons and axion-like particles in the very forward direction at the High Luminosity LHC. Such particles can penetrate up to 50 m of iron and then decay inside a 14 m$^3$ vacuum pipe made by enlarging an 18 m long section of the LHC pipe to a radius of 50 cm.
