Sum Rules for Light-by-Light Scattering [PDF]
We derive a set of sum rules for the light-by-light scattering and fusion: $ \to all$, and verify them in lowest order QED calculations. A prominent implication of these sum rules is the superconvergence of the helicity-difference total cross-section for photon fusion, which in the hadron sector reveals an intricate cancellation between the ...

Dynamic light scattering imaging [PDF]
Nature of red blood cell dynamics and light scattering interactions unraveled to accurately probe cerebral blood flow. We introduce dynamic light scattering imaging (DLSI) to enable the wide-field measurement of the speckle temporal intensity ...

Dispersive approach to hadronic light-by-light scattering [PDF]
Based on dispersion theory, we present a formalism for a model-independent evaluation of the hadronic light-by-light contribution to the anomalous magnetic moment of the muon. In particular, we comment on the definition of the pion pole in this framework and provide a master formula that relates the effect from pi pi intermediate states to the partial ...

All‐inorganic perovskite quantum dots (QDs) CsPbX3 (X = Cl, Br, and I) have recently emerged as a new promising class of X‐ray scintillators. However, the instability of perovskite QDs and the strong optical scattering of the thick opaque QD scintillator

Rigorous bounds on light-by-light scattering
Abstract We bound EFT coefficients appearing in 2 → 2 photon scattering amplitudes in four dimensions. After reviewing unitarity and positivity conditions in this context, we use dispersion relations and crossing symmetry to compute sum rules and null constraints. This allows us to derive new rigorous bounds on operators with four,
