Probing $D_{s}^{+} \to η^{(')} ℓ^{+} ν_{ℓ}$ semileptonic decay within LCSR under chiral heavy quark effective field theory

Ruiyu Zhou, Hai-Bing Fu, Yi Zhang +1

Motivated by the successful application of Heavy Quark Effective Field Theory in describing decays from heavy to light mesons, this work explores its applicability to the semilepto…
