      abstract     = {The breaking of $U(1)_R$ symmetry plays a crucial role in
                      modeling the breaking of supersymmetry (SUSY). In the models
                      that possess both SUSY preserving and SUSY breaking vacua,
                      tube-like cosmic strings called R-tubes, whose surfaces are
                      constituted by domain walls interpolating a false and a true
                      vacuum with some winding numbers, can exist. Their
                      (in)stability can strongly constrain SUSY breaking models
                      theirselves. In the present study, we investigate the
                      dynamical (in)stability of two colliding metastable
                      tube-like strings by field-theoretic simulations. From them,
                      we find that the strings become unstable, depending on the
                      relative collision angle and speed of two strings, and the
                      false vacuum is eventually filled out by the true vacuum
                      owing to rapid expansion of the strings or unstable bubbles
                      created as remnants of the collision.},
