In this paper, we investigate the time-dependent angular analysis of Bs0 → ϕϕ decay to search for new physics signals via CP-violating observables. We work with a new physics Hamiltonian containing both left- and right-handed Chromomagnetic dipole operators. The hierarchy of the helicity amplitudes in this model gives us a new scheme of experimental search, which is different from the ones LHCb has used in its analysis. To illustrate this new scheme, we perform a sensitivity study using two pseudo datasets generated using LHCb's measured values. We find the sensitivity of CP-violating observables to be of the order of 5-7% with the current LHCb statistics. Moreover, we show that Belle(II)'s B0d → ϕKs and LHCb's Bs0 → ϕϕ measurements could be coupled within our model to obtain the chirality of the new physics.
