Through gravity/gauge duality, the string breaking and running couplingconstant of heavy quark-antiquark pair are investigated in the rotatingbackground. For the meson decay mode $\rm Q\bar{Q} \rightarrow Q\bar{q}+\bar{Q} q$, we discuss the string breaking and running coupling in theparallel and transverse case. It is found that the parallel case has a moresignificant on string breaking and running coupling constant than thetransverse case in the confined phase. The string-breaking distance and themaximum value of running coupling will decrease with the increase of angularvelocity in the parallel case. Besides, we also investigate the runningcoupling and screening distance at finite angular velocity in the deconfinedphase. It is found that the maximum values of the running coupling andscreening distance are decreasing functions of angular velocity. The parallelcase has a more significant influence on the running coupling and screeningdistance than the transverse case in the deconfined phase.
