Gamma-Ray Bursts (GRBs) are very energetic cosmological transients. Long GRBsare usually associated with Type Ib/c Supernovae (SNe), and we refer to them asGRB-SNe. Since the associated SN for a given GRB is observed only at lowredshift, a possible selection effect exists when we consider intrinsicallyfaint sources which cannot be observed at high redshift. Thus, it is importantto explore the possible relationships between GRB and SN parameters after thesehave been corrected for astrophysical biases due to the instrumental selectioneffects and redshift evolution of the variables involved. So far, only GRBprompt emission properties have been checked against the SNe Ib/c propertieswithout considering the afterglow (AG). This work investigates the existence ofrelationships among GRB's prompt and AG and associated SN properties. Weinvestigate 91 bidimensional correlations among the SN and GRB observablesbefore and after their correction for selection biases and evolutionaryeffects. As a result of this investigation, we find hints of a new correlationwith a Pearson correlation coefficient > 0.50 and a probability of being drawnby chance < 0.05. This correlation is between the luminosity at the end of theGRB optical plateau emission and the rest-frame peak time of the SN. Accordingto this relation, the brightest optical plateaus are accompanied by the largestpeak times. This correlation is corrected for selection biases and redshiftevolution and may provide new constraints for the astrophysical modelsassociated with the GRB-SNe connection.
