We consider inflaton decay to final state bosons with self-interactions of moderate strength. We find that such final state self-interactions qualitatively alter the reheat dynamics. In the case of narrow-band resonance decay, where a…
We estimate effects of the final state interactions in B -> pi pi decays coming from rescattering of pi pi via exchange of rho, sigma, f_0 mesons. Then we include the rho rho rescattering via exchange of pi, omega, a_1 mesons and finally we…
We estimate final state interactions in the B-meson decays into two light vector mesons by the Regge model. We consider Pomeron exchange and charmed Regge trajectories that can relate intermediate charmed particles to the final state. The…

The model is presented to describe the f_2(1270) meson photoproduction as a result of pion-pion interactions in the final state. Treating tensor mesons as objects dynamically created due to final state interactions is a convenient and…

In this article, we study the final-state rescattering effects in the decays $B^0\to \chi_{c0}K^{*0}$ and $B^+ \to \chi_{c0}K^{*+}$, and observe the corrections are zero in the SU(3) limit, which is warranted by the heavy quark symmetry. It…
Available experimental data on decay rates for B --> \psi K, and decay rates and transversity amplitudes for B --> \psi K^* are used to investigate nonfactorization contributions in these decays using five different theoretical models for…
We study the effects of mesonic final state interactions on the Hanbury Brown and Twiss (HBT) intensity interferometry for mesons in ultra-relativistic heavy ion collisions. Modification of the one-body amplitude of emitted mesons while…
To understand the short-distance vs long-distance final-state interactions, we have performed a detailed amplitude analysis for the two-body decay, J/psi into vector and pseudoscalar mesons. The current data favor a large relative phase…
