    <subfield code="a">&lt;p&gt;This thesis presents a study of resolution monitoring for the Belle II electromagnetic calorimeter using the process e+e&amp;minus;&amp;rarr;&amp;mu;+&amp;mu;&amp;minus;&amp;gamma;e^+e^- \to \mu^+\mu^-\gammae+e&amp;minus;&amp;rarr;&amp;mu;+&amp;mu;&amp;minus;&amp;gamma;. Based on Monte Carlo simulations from the 2022 data taking periods, the work explores the extraction of energy and angular resolution under realistic background and occupancy conditions.&lt;/p&gt;

&lt;p&gt;The results indicate that energy resolution is sensitive to detector occupancy, quantified by the number of out-of-time clusters, while angular resolution shows little dependence on these conditions. The analysis highlights the complementary behaviour of energy and angular observables and discusses their potential usefulness for detector performance studies during Belle II operations.&lt;/p&gt;</subfield>
