英文摘要	We perform a systematic exploration of the possible doubly charmed molecular pentaquarks composed of Sigma(()(c)()) D-(()) with the one-boson-exchange potential model. After taking into account the S - D wave mixing and the coupled channel effects, we predict several possible doubly charmed molecular pentaquarks, which include the Sigma D-c with I(J(P)) = 1/2(1/2(-)), Sigma(c)D with 1/2(3/2(-)), and Sigma D-c with 1/2(1//2(-)), 1/2(3/2(-)). The Sigma D-c state with 3/2(1/2(-)) and Sigma D-c* state with 3/2(1/2(-)) may also be suggested as candidates of doubly charmed molecular pentaquarks. The Sigma D-c and Sigma(c)D states can be searched for by analyzing the Lambda D-c pi invariant mass spectrum of the bottom baryon and B meson decays. The Sigma D-c states can be searched for in the invariant mass spectrum of Lambda D-cpi, Lambda D-c pi pi and Lambda D-c pi gamma. Since the width of Sigma(c) is much larger than that of D, Sigma(c)D -> Lambda D-c pi will be the dominant decay mode. We sincerely hope these candidates for the doubly charmed molecular pentaqurks will be searched by LHCb or Bellell collaboration in the near future. (C) 2021 The Author(s). Published by Elsevier B.V.
