1. Pion electromagnetic form factor at high precision with implications to aμππ and the onset of perturbative QCD / Ananthanarayan, B. ; Caprini, Irinel ; Das, Diganta
We extend recently developed methods used for determining the electromagnetic charge radius and aμππ to obtain a determination of the electromagnetic form factor of the pion, FπV(t), in several significant kinematical regions, using a parametrization-free formalism based on analyticity and unitarity, with the inclusion of precise inputs from both timelike and spacelike regions.

3. On the angular distribution of Λ b → Λ(→ N π)τ + τ − decay / Das, Diganta
We present a full angular distribution of the four body Λ b → Λ(→ N π)ℓ + ℓ − decay where the leptons are massive and the Λ b is unpolarized, in an operator basis which includes the Standard Model operators, new vector and axial-vector operators, and scalar and pseudo-scalar operators. [...]

5. The B ¯ → K ¯ πℓℓ $$ \overline{B}\to \overline{K}\pi \ell \ell $$ and B ¯ s → K ¯ Kℓℓ $$ {\overline{B}}_s\ \to \overline{K}K\ell \ell $$ distributions at low hadronic recoil / Das, Diganta ; Hiller, Gudrun ; Jung, Martin ; Shires, Alex
The rare multi-body decays B ¯ → K ¯ πℓℓ $$ \overline{B}\to \overline{K}\pi \ell \ell $$ and B ¯ s → K ¯ Kℓℓ $$ {\overline{B}}_s\ \to \overline{K}K\ell \ell $$ are both important as backgrounds to precision analyses in the benchmark modes B ¯ → K ¯ * ℓℓ $$ \overline{B}\to {\overline{K}}^{*}\ell \ell $$ and B ¯ s → ϕℓℓ $$ {\overline{B}}_s\to \phi \ell \ell $$ as well as sensitive probes of flavor physics in and beyond the standard model.
