We consider a highly unconventional superconducting state with chiral d-wave symmetry in doped graphene under strain with the Gutzwiller-RVB method in the momentum space.It is shown that flat bands emerge in the normal state for reasonable strain.As a result,the superconducting critical temperature is found to be linearly proportional to the strength of the electron-electron interaction.Furthermore,the chiral d-wave superconducting state is shown with coexistence of the charge density wave and the pair density wave.There are different coexisting states with those orders under different doping levels.
