    "abstract": "The Lax pair for a derivative nonlinear Schr\\\"{o}dinger equation proposed by\nChen-Lee-Liu is generalized into matrix form. This gives new types of\nintegrable coupled derivative nonlinear Schr\\\"{o}dinger equations. By virtue of\na gauge transformation, a new multi-component extension of a derivative\nnonlinear Schr\\\"{o}dinger equation proposed by Kaup-Newell is also obtained.",
