The performance of the TA $\times$ 4 surface detector array: 4.3 years of the first-half expansion

Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126

The Telescope Array (TA) experiment aims to reveal the origin of ultra-high-energy cosmic rays (UHECRs) by observing air showers using surface detectors (SDs), which spread over an…

Charged-lepton identification at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +409

Effective particle identification capabilities are a strategic priority for the physics program of the Belle~II experiment. We describe the algorithms used at Belle~II for identify…

First evidence of $X (3872) \to I ¨ ^{0} I ¨ _{c 0} (1 P)$ and search for $X (3915) \to I ¨ ^{0} I ¨ _{c 1} (1 P)$

Belle, Belle II Collaborations, : +412

We search for the pionic transitions $X (3872) \to I ¨ ^{0} I ¨ _{c J} (1 P)$ $(J = 0, 1, 2)$ and $X (3915) \to I ¨ ^{0} I ¨ _{c 1}$ in $B^{+} \to I ¨ ^{0} I ¨ _{c J} K^{+}$ decays using the Belle and Belle~II data sam…

Measurement of mixing-induced CP violation in the decay $B^{0} \to I ¨ ^{0} I ¨ ^{0}$

Belle II Collaboration, M. Abumusabh, I. Adachi +437

Measurements of charge-parity (CP) violation in quark transitions provide stringent tests of the current theory and sensitive probes of particles or interactions beyond it. We repo…

Observation of the radiative decay $D_{s} (2317)^{+} \to D_{s}^{*} I^^{3}$

Belle II Collaboration, M. Abumusabh, I. Adachi +367

We observe the radiative decay $D_{s 0}^{*} (2317)^{+} \to D_{s}^{*+} I^^{3}$ for the first time, with a significance exceeding $10$ standard deviations. The signal is found in the conti…
