Improved transition form factors at next-to-leading order in light cone sum rules
Arslan Sikandar, M. Jamil Aslam
We present an improved determination of the transition form factors using light-cone sum rules (LCSR) with an expansion near the light cone. We include the one-l…

Symmetry-Breaking Effects on Form Factors and Observables in Decay
Saba Ayub, Saba Shafaq, Arslan Sikandar +1
In the heavy-quark and large-energy limits, symmetry relations reduce the number of independent form factors governing heavy-to-light -meson decays. Exploiting these relations,…
