Qcombo: A Python Package for Automated Commutator Calculations of Quantum Many-Body Operators

L. H. Chen, Y. Li, H. Hergert +1

The paper introduces Qcombo, a Python package that automates symbolic commutator calculations for quantum many-body operators using the generalized Wick theorem, and demonstrates i…

Searches for charged-lepton-flavor violation in $χ_{b J} (1 P)$ decays

Belle, Belle II Collaborations, : +425

We report the first searches for charged-lepton-flavor violation in decays of $χ_{b J} (1 P)$ ( $J = 0, 1,$ and $2$ ) to a pair of charged leptons using 158 million $Υ (2 S)$ decays collect…

Study of $B^{+} \to I^¼^{+} I^½_{I^} ¼$ decays at Belle and Belle II

Belle, Belle II Collaborations, : +412

We report a measurement of the branching fraction for the leptonic decay $B^{+} \to I^¼^{+} I^½_{I^} ¼$ . This work presents the first $B^{+} \to I^¼^{+} I^½_{I^} ¼$ result using Belle~II data, an updated Be…

Study of $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ (h = I ¨ , K, p)$ via initial-state radiation at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +417

Using a data sample of 427.9 fb $^{- 1}$ collected by the Belle~II detector at or near the $I^¥ (4 S)$ and $I^¥ (10753)$ resonances, the cross sections for $e^{+} e^{-} \to h^{+} h^{-} J / I ¨ $ $(h=Ï/K…

Evidence of Spin-Interference Effects in Exclusive $J / I ¨ \to e^{+} e^{-}$ Photoproduction in Ultraperipheral Heavy-Ion Collisions

The STAR Collaboration

We report the first evidence of spin interference in exclusive $J / I ¨ \to e^{+} e^{-}$ photoproduction in ultraperipheral heavy-ion collisions at STAR at $s_{N N} = 200$ ~GeV. In Au+…
