直线对撞机上类属接触相互作用中双喷流的产生

Dijet production in generic contact interaction at linear colliders

Swapan Majhi

摘要:

我们考虑在一类有效理论中,在$e^+ e^-$对撞机上双喷流的产生,相关的算符是四费米子接触相互作用。尽管相互作用的nonrenormalizable性质,我们明确表明,计算QCD修正是可能的和有意义的。计算各种差分分布的校正,我们表明,这些可以是实质性的,显着不同的SM内。此外,校正具有非常独特的风味依赖性。

英文摘要:

We consider dijet production at a $e^+ e^-$ collider in a class of effective theories with the relevant operators being four-fermion contact interaction. Despite the nonrenormalizable nature of the interaction, we explicitly demonstrate that calculating QCD corrections is both possible and meaningful. Calculating the corrections for various differential distributions, we show that these can be substantial and significantly different from those within the SM. Furthermore, the corrections have a very distinctive flavor dependence.
