We explore the effect of ionizing UV background (UVB) on the redshift spaceclustering of low-$\textit{z}$ ($\textit{z} \leq 0.5$) OVI absorbers usingSherwood simulations incorporating "WIND" (i.e. outflows driven by stellarfeedback) only and "AGN+WIND" feedbacks. These simulations show a positiveclustering signals up to a scale of 3 Mpc. We find that the effect of feedbackis restricted to small scales (i.e $\leq$ 2 Mpc or 200 $\textit{kms}^{-1} $ at$\textit{z}$ ~ 0.3) and "WIND" only simulations produce stronger clusteringsignal compared to simulations incorporating "AGN+WIND" feedbacks. Howclustering signal is affected by the assumed UVB depends on the feedbackprocesses assumed. For the simulations considered here the effect of UVB isconfined to even smaller scales (i.e <1 Mpc or $\approx 100\textit{kms}^{-1}$at $\textit{z}$ ~ 0.3). These scales are also affected by exclusion caused byline blending. Therefore, our study suggests clustering at intermediate scales(i.e 1-2 Mpc for simulations considered here) together with the observed columndensity distribution can be used to constrain the effect of feedback insimulations.
