Analysis note: Long-range near-side correlation in $e^{+} e^{-}$ with $W$ -boson-pair events at 183-209 GeV with ALEPH archived data

Tzu-An Sheng, Yu-Chen Chen, Yi Chen +12

Events characterized by a high multiplicity of charged particles have been a central focus in the study of collective behavior across both large and small collision systems. A prev…

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…

Novel method to indirectly reconstruct neutrinos in collider experiments

Hongrong Qi, Paoti Chang

Neutrinos play a crucial role in particle physics, but cannot be tracked in collider experiments. If more than one neutrino is present in a collision event, it is impossible to ext…

Study of $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I^¥ (1 D)$ at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +404

The bottomonium spectrum, consisting of bound states of a $b$ quark and an anti- $b$ quark, provides an excellent laboratory for probing quantum chromodynamics in the non-perturbati…

Search for $C P$ violation in $I^_{c}^{+} \to I^£^{+} h^{+} h^{-}$ and $I^_{c}^{+} \to p h^{+} h^{-}$ at Belle II

Belle II Collaboration, M. Abumusabh, I. Adachi +344

We report decay-rate $C P$ asymmetries of the singly-Cabibbo-suppressed decays $I^_{c}^{+} \to I^£^{+} h^{+} h^{-}$ and $I^_{c}^{+} \to p h^{+} h^{-}$ , with $h = K, I ¨ $ , measured using 428 fb $^{- 1}$ of $e^{+} e^{-}$ …

Search for Pcs(4459) and Pcs(4338) in Upsilon(1S,2S) inclusive decays at Belle

I. Adachi, L. Aggarwal, H. Ahmed +402

Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we search f…
