Higgs产生作为反常顶部耦合的探测器

Higgs production as a probe of anomalous top couplings

Debajyoti Choudhury, Pratishruti Saha

摘要:

大型强子对撞机目前可能正在看到希格斯玻色子的第一个线索。在大型强子对撞机中,希格斯粒子的主要产生模式涉及顶夸克环。因此,对希格斯粒子产生截面和衰变宽度的精确测量可以用来获得对反常顶部耦合的限制。我们发现,这样的练习可能会产生的约束,是强于那些来自低能量的观测以及直接的边界预期从顶部对生产过程。

英文摘要:

The LHC may be currently seeing the first hints of the Higgs boson. The dominant production mode for the Higgs at the LHC involves a top-quark loop. An accurate measurement of Higgs production cross-sections and decay widths can thus be used to obtain limits on anomalous top couplings. We find that such an exercise could potentially yield constraints that are stronger than those derived from low-energy observables as well as direct bounds expected from the top pair-production process.
