Description

I will discuss how the novel CP-phases, potentially present in New physics solutions to observed LFU ratios in b-hadron decays, could be revealed. For R_K() I will argue that a novel CP phase in NP amplitudes of b -> s mu mu could be observed either in mixing-induced asymmetries
or in direct CP-asymmetries which are enhanced by narrow charmonium resonances. The correlation with constraints from meson mixing will be discussed in concrete models. In charged current amplitudes from NP that explain R_D^{
} I will show that some leptoquark scenarios require large
novel CP phase. I will present possibilities to constrain such CP phases in direct collider searches.
