FACET项目:前向孔径CMS ExTension,用于寻找新的长寿命粒子

The FACET Project: Forward Aperture CMS ExTension to search for new Long-Lived Particles

Michael G Albrow

摘要:

FACET是CMS在高亮度LHC上提出的一个新的子系统,用于寻找暗光子、暗希格斯粒子、重中性轻子和类轴子等正向的入口粒子。这种粒子可以穿透高达50米的铁,然后在14米长的$^3$真空管中衰变,该真空管是通过将LHC管道的18米长部分扩大到50厘米的半径制成的。

英文摘要:

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.
