    "description": "Altermagnetism exhibits unique physical properties such as spin-momentum locking, anomalous Hall effect, nontrivial topological phase, and giant magnetoresistance. Among all the predicted candidates, several room temperature altermagnets are suggested to host significant potential applications. RuO\u2082 has been proposed as the most promising candidate. However, recently, there is intense debate about whether RuO\u2082 exhibits magnetic order or not. Experiments by several different technologies claim the collinear magnetic order and spin splitting induced effects. However, very recent \u03bcSR results reveal no magnetic order in RuO\u2082 which indicates that the time reversal symmetry is not broken. Direct observation of the high-resolution bulk band structure is absent up to date, but essential to investigate the electronic structure of RuO\u2082. In this study, utilizing soft X-ray ARPES, we report systematic direct experimental observation of bulk band structure of RuO\u2082. We observed signature of bulk band splitting induced by unknown symmetry broken. The ARPES data and calculated band structureare attached in this record.",
