      abstract     = {Femtoscopic correlations with the particle pair
                      combinations $K_S^0K_S^0$ and $K_S^0K^\pm$ are studied in pp
                      collisions at $\sqrt{s}$ = 5.02 and 13 TeV by the ALICE
                      experiment. At both energies, boson source parameters are
                      extracted for both pair combinations, by fitting models
                      based on Gaussian size distributions of the sources, to the
                      measured two-particle correlation functions. The interaction
                      model used for the $K_S^0K_S^0$ analysis includes quantum
                      statistics and strong final-state interactions through the
                      f$_0$(980) and $a_0$(980) resonances. The model used for the
                      $K_S^0K^\pm$ analysis includes only the final-state
                      interaction through the a0 resonance. Source parameters
                      extracted in the present work are compared with published
                      values from pp collisions at $\sqrt{s}$ = 7 TeV and the
                      different pair combinations are found to be consistent. From
                      the observation that the strength of the $K_S^0K_S^0$
                      correlations is significantly greater than the strength of
                      the $K_S^0K^\pm$ correlations, the new results are
                      compatible with the $a_0$ resonance being a tetraquark state
                      of the form ($q_1$,$\bar{q_2}$,$s$,$\bar{s}$), where $q_1$
                      and $q_2$ are u or d quarks.},
