Abstract
Let \(\zeta (s)\) and Z(t) be the Riemann zeta function and Hardy’s function respectively. We show asymptotic formulas for \(\int _0^T Z(t)\zeta (1/2+it)dt\) and \(\int _0^T Z^2(t) \zeta (1/2+it)dt\). Furthermore we derive an upper bound for \(\int _0^T Z^3(t) \chi ^{\alpha }(1/2+it)dt\) for \(-1/2<\alpha <1/2\), where \(\chi (s)\) is the function which appears in the functional equation of the Riemann zeta function: \(\zeta (s)=\chi (s)\zeta (1-s)\).
