Construction of the $$a_4$$ family

Abstract The COMPASS Collaboration recently reported a new broad $$J^{PC}=4^{++}$$ J PC = 4 + + structure, denoted as $$a_4(2610)$$ a 4 ( 2610 ) , which has sparked our interest in studying the $$a_4$$ a 4 family with $$I^GJ^{PC}=1^{-}4^{++}$$ I G J PC = 1 - 4 + + . In this work,...
