Regularized Compton double scattering via unitarity

Shanmuka Shivashankara, Isra Gashi

When two initially entangled photons each undergo Compton scattering, the scattered electrons become correlated. However, the final reduced density matrix of one scattered pair is…

Entanglement Entropy Distributions of a Muon Decay

Shanmuka Shivashankara, Patti Rizzo, Nicole Cafe

Divergences that occur in density matrices of decay and scattering processes are shown to be regularized by tracing and unitarity or the optical theorem. These divergences are regu…

$Λ_{b} \to Λ_{c} τ ν ˉ_{τ}$ Decay in the Standard Model and with New Physics

Shanmuka Shivashankara, Wanwei Wu, Alakabha Datta

Recently hints of lepton flavor non-universality emerged when the BaBar Collaboration observed deviations from the standard model predictions in $R(D^{(*)}) \equiv {\cal B}({\bar B…

Simultaneous Explanation of the $R_{K}$ and $R (D^{(*)})$ Puzzles

Bhubanjyoti Bhattacharya, Alakabha Datta, David London +1

At present, there are several hints of lepton flavor non-universality. The LHCb Collaboration has measured $R_{K} \equiv B (B^{+} \to K^{+} μ^{+} μ^{-}) / B (B^{+} \to K^{+} e^{+} e^{-})$ , a…
