强子对撞机上的Mu-Tau产生

Mu-Tau Production at Hadron Colliders

Tao Han, Ian Lewis, Marc Sher

摘要:

受大的nu_mu-nu_tau味道混合的启发,我们考虑在强子对撞机上通过6维有效算子产生mu-tau,这可以归因于更高尺度Lambda下味道部门的新物理。目前的限制,许多这些运营商从低能实验是非常弱或不存在的,他们可能会导致清洁的mu+tau-和mu-tau+信号在强子对撞机。在Tevatron与8个反femtobarns,一个可以超过目前的界限,大多数运营商,与大多数2西格玛灵敏度在6-24 TeV的范围。我们发现,在LHC与1(100)反femtobarns积分亮度,可以达到2西格玛的灵敏度为λ \sim 3-10 TeV(λ = \sim 6-21 TeV),这取决于洛伦兹结构的运营商。对于一些运营商,几个数量级的灵敏度的改善,可以得到只有几十个逆皮巴在大型强子对撞机。

英文摘要:

Motivated by large nu_mu-nu_tau flavor mixing, we consider mu-tau production at hadron colliders via dimension-6 effective operators, which can be attributed to new physics in the flavor sector at a higher scale Lambda. Current bounds on many of these operators from low energy experiments are very weak or nonexistent, and they may lead to clean mu+tau- and mu-tau+ signals at hadron colliders. At the Tevatron with 8 inverse femtobarns, one can exceed current bounds for most operators, with most 2 sigma sensitivities being in the 6-24 TeV range. We find that at the LHC with 1 (100) inverse femtobarns integrated luminosity, one can reach a 2 sigma sensitivity for Lambda \sim 3-10 TeV (Lambda =\sim 6-21 TeV), depending on the Lorentz structure of the operator. For some operators, an improvement of several orders of magnitude in sensitivity can be obtained with only a few tens of inverse picobarns at the LHC.
