The rotating string model is an effective model of mesons, in which the quarkand the antiquark are linked by a straight string. We previously developed anew framework to include the retardation effects in the rotating string model,but the string was still kept straight. We now go a step further and show thatthe retardation effects cause a small deviation of the string from the straightline. We first give general arguments constraining the string shape. Then, wefind analytical and numerical solutions for the string deformation induced byretardation effects. We finally discuss the influence of the curved string onthe energy spectrum of the model.Comment: 3 figure
