Assuming generic flavor–conserving ALP couplings to SM fermions and a generic ALP mass, ma, the latest experimental results for pseudo–scalar leptonic decays are used to provide updated bounds on the ALP–fermion Lagrangian sector. Constrains on the ALP-quark couplings obtained from these channels are not yet competitive with the ones derived from FCNC processes, like M→Pa decays. These leptonic decays can, however, provide the most stringent model–independent upper bounds on ALP-leptons couplings for ma in the (sub)–GeV range. 000118086 536__ $$9info:eu-repo/grantAgreement/ES/DGIID-DGA/2015-E24-2$$9info:eu-repo/grantAgreement/ES/DIIU-DGA/European Social Fund$$9info:eu-repo/grantAgreement/EC/H2020/674896/EU/The Elusives Enterprise: Asymmetries of the Invisible Universe/ELUSIVES$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 674896-ELUSIVES$$9info:eu-repo/grantAgreement/EC/H2020/690575/EU/InvisiblesPlus/InvisiblesPlus$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 690575-InvisiblesPlus$$9info:eu-repo/grantAgreement/EC/H2020/860881/EU/Revealing how hidden symmetries shape the universe/HIDDeN$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 860881-HIDDeN$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2015-65745-P$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00$$9info:eu-repo/grantAgreement/ES/UZ-IBERCAJA-CAI/CB5-21 000118086 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000118086 590__ $$a2.8$$b2022 000118086 592__ $$a0.938$$b2022 000118086 591__ $$aPHYSICS, PARTICLES & FIELDS$$b15 / 29 = 0.517$$c2022$$dQ3$$eT2 000118086 593__ $$aNuclear and High Energy Physics$$c2022$$dQ2 000118086 594__ $$a5.8$$b2022 000118086 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000118086 700__ $$aGuerrera, A.W.M. 000118086 700__ $$0(orcid)0000-0002-9408-4406$$aPeñaranda, S.$$uUniversidad de Zaragoza 000118086 700__ $$aRigolin, S. 000118086 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
