      abstract     = {We propose a new theory framework to study the electroweak
                      radiative corrections in Kl3 decays by combining the classic
                      current algebra approach with the modern effective field
                      theory. Under this framework, the most important O(GFα)
                      radiative corrections are described by a single tensor Tμν
                      involving the time-ordered product between the charged weak
                      current and the electromagnetic current, and all remaining
                      pieces are calculable order-by-order in Chiral Perturbation
                      Theory. We further point out a special advantage in the K0l3
                      channel that it suffers the least impact from the
                      poorly-constrained low-energy constants. This finding may
                      serve as a basis for a more precise extraction of the matrix
                      element Vus in the future.},
