Abstract
The new physics (NP) is parametrized with four model-independent quantities: the magnitudes and phases of the dispersive part M12 and the absorptive part Γ12 of the NP contribution to the effective Hamiltonian. We constrain these parameters using the four observables ΔMs, ΔΓs, the mixing phase \(\beta_\mathrm{s}^{J/\psi\phi}\) and \(A^b_{\rm sl}\). This formalism is extended to include charge-parity-time reversal (CPT) violation, and it is shown that CPT violation by itself, or even in the presence of CPT-conserving NP without an absorptive part, helps only marginally in the simultaneous resolution of these anomalies.
