In this work our purpose is to calculate the pion radiative decay constant using the formulation of Bethe-Salpeter equation under covariant Instantaneous Ansatz(CIA)after inclusion of both leading(LO) as well as next-to-leading(NLO) terms in the BS wave function of the pion. In this process we also calculate the pion Bethe-Salpeter  Normalizer which is an extremely lengthy calculation.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783847339038\"\u003e\u003ch3\u003eIn Bethe-Salpeter Framework\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783847339038","offer_id":39493594218589,"sku":"9783847339038","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/377015a0-9b4d-4001-9db3-5ba748201e06.jpg?v=1758259835","url":"https:\/\/shop.autorenwelt.de\/en\/products\/radiative-decay-constant-of-pion-von-abebe-gucho","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
