Screening length of a heavy quark–antiquark pair in non-commutative plasma

We investigate the screening length of a heavy quark–antiquark (\(Q{\bar{Q}}\)) pair in non-commutative \({\mathcal {N}}=4\) super Yang–Mills plasma at strong coupling. We perform the analysis by computing the Wilson loop in a boosted background and consider the axis of the \(Q{\bar{Q}}\) pair along different directions. It turns out that the inclusion of non-commutativity increases the screening length, thus enhancing the binding energy of the \(Q{\bar{Q}}\) pair. Furthermore, the presence of non-commutativity reduces quarkonium dissociation, in agreement with previous findings of the imaginary potential and entropic force.
