中性$\textbf{D}\rightarrow\textbf{VV}$模中的新物理

New physics in neutral $\textbf{D}\rightarrow\textbf{VV}$ modes

Aritra Biswas, Sanjoy Mandal

摘要:

通过对中性$D$介子的含时分析,我们证明了在$D^0\rightarrow VV$模中,可以构造观测量来检验新物理的存在。我们表明,它是可能的,以确定是否NP是由于衰变,混合或两者的组合。我们还提供了数值估计的偏振振幅的$D^0\rightarrow\overline{K^{*0}}ρ^0$模式,并表明我们的分析是一致的,与目前的数据。

英文摘要:

We show that it is possible to construct observables to test the existence of new physics in a model independent way for the $D^0\rightarrow VV$ modes using a time-dependent analysis of the neutral $D$ meson. We show that it is possible to identify whether the NP is due to decay, mixing or a combination of both. We also provide numerical estimates for the polarization amplitudes for the $D^0\rightarrow\overline{K^{*0}}ρ^0$ mode and show that our analysis is consistent with the present data.
