Summary, etc. <p class="Abstract">The fusion and subsequent decay analysis of Z=116 superheavy nucleus formed via <sup>48</sup>Ca+<sup>248</sup>Cm→<sup>296</sup>Lv<sup>*</sup>, <sup>50</sup>Ti+<sup>244</sup>Pu→<sup>294</sup>Lv<sup>*</sup>,and <sup>58</sup>Fe+<sup>232</sup>Th→<sup>290</sup>Lv<sup>* </sup>reactions is carried out using extended ℓ-summed Wong model and dynamical cluster decay model (DCM), respectively. First of all, the experimentally available fusion-fission (A/2±20) data is adequately addressed for <sup>296</sup>Lv<sup>* </sup>and <sup>294</sup>Lv<sup>*</sup> superheavy nuclei using extended ℓ-summed Wong model and the predictions are made for fusion-fission excitation function of <sup>290</sup>Lv<sup>* </sup>nucleus. It is observed that with decrease in mass-asymmetry (η), the contribution of fusion-fission component decreases. This drop is steeper for <sup>50</sup>Ti to <sup>58</sup>Fe as compared to that for <sup>48</sup>Ca to <sup>50</sup>Ti. The calculated values of compound nucleus formation probability (P<sub>CN</sub>) are highest for <sup>48</sup>Ca followed by <sup>50</sup>Ti and <sup>58</sup>Fe. Finally, the mass distribution of decay fragments is studied for <sup>296</sup>Lv<sup>*</sup>, <sup>294</sup>Lv<sup>*</sup>, and <sup>290</sup>Lv<sup>* </sup>nuclei using DCM at near barrier energies. A valley in A<sub>CN</sub>/2 region results in asymmetric mass distribution for <sup>296</sup>Lv<sup>*</sup> which becomes relatively symmetric for the lighter isotope <sup>290</sup>Lv<sup>*</sup>.</p>
