Phys. ; UC, Santa Cruz (main)) ; Athron, Peter (Nanjing Normal U.) ; Bai, Xiaozhi (USTC, Hefei) ; Calibbi, Lorenzo (Nankai U.) ; Cao, Lu (Fudan U., Shanghai ; DESY) ; Che, Yuzhi (Beijing, Inst. High Energy Phys. ; UCAS, Beijing) ; Chen, Chunhui (Iowa State U.) ; Chen, Ji-Yuan (Shanghai Jiaotong U.) ; Chen, Long (Shandong U.) et al.
We discuss the landscape of flavor physics at the Circular Electron-Positron Collider (CEPC), based on the nominal luminosity outlined in its Technical Design Report. The CEPC is designed to operate in multiple modes to address a variety of tasks. [...]

Quenching of single-particle strength inferred from nucleon-removal transfer reactions on $^{15}$C
/ Jiang, Y.C. (SUSTech, Shenzhen ; Beijing, Inst. Atomic Energy) ; Chen, J. (SUSTech, Shenzhen ; Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A.

(Argonne) et al.
The difference in the proton and neutron separation energies ($ΔS$) of the weakly bound $^{15}$C ground state is -19.86 MeV, an extreme value. Data from intermediate-energy heavy-ion induced (HI-induced) knockout reactions on nuclei spanning $-20\lesssimΔS\lesssim+20$ MeV, suggest that the degree to which single-particle strength is quenched, $R\mathrm{_{s}}$, has a negative correlation with $ΔS$, decreasing from unity around $-20$~MeV to around 0.2 at $+20$~MeV.

The anomalous magnetic moment of the muon in the Standard Model: an update

(Sao Paulo U., Sao Carlos) ; Bruno, M. (Milan Bicocca U. ; INFN, Milan Bicocca) et al.
We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_μ$, updating the first White Paper (WP20) [1]. The pure QED and electroweak contributions have been further consolidated, while hadronic contributions continue to be responsible for the bulk of the uncertainty of the SM prediction. [...]

Compound-Nucleus and Doorway-State Decays of $\beta$-delayed Neutron Emitters $^{51, 52, 53}\mathrm{K}$

We investigated decays of $^{51, 52, 53}\mathrm{K}$ at the ISOLDE Decay Station at CERN in order to understand the mechanism of the $\beta$-delayed neutron-emission ($\beta n$) process. The experiment quantified neutron and $\gamma$-ray emission paths for each precursor [...]

Review of particle physics, 2024-2025
/ Particle Data Group Collaboration
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,717 new measurements from 869 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons [...]

Evolution of the nuclear spin-orbit splitting explored via the $^{32}$Si($d$,$p$)$^{33}$Si reaction using SOLARIS
/ Chen, J. (SUSTech, Shenzhen ; Argonne) ; Kay, B.P. (Argonne) ; Hoffman, C.R. (Argonne) ; Tang, T.L. (Argonne) ; Tolstukhin, I.A. (Argonne) ; Bazin, D. (Michigan State U.) ; Lubna, R.S. (Michigan State U.) ; Ayyad, Y. (Santiago de Compostela U., IGFAE) ; Beceiro-Novo, S. (Michigan State U.) ; Coombes, B.J. (Australian Natl. U., Canberra) et al.
The spin-orbit splitting between neutron 1$p$ orbitals at $^{33}$Si has been deduced using the single-neutron-adding ($d$,$p$) reaction in inverse kinematics with a beam of $^{32}$Si, a long-lived radioisotope. Reaction products were analyzed by the newly implemented SOLARIS spectrometer at the reaccelerated-beam facility at the National Superconducting Cyclotron Laboratory. [...]

High-precision mass measurements of exotic $^{95-97}$Ag isotopes close to the $N = Z$ line have been conducted with the JYFLTRAP double Penning trap mass spectrometer, with the silver ions produced using the recently commissioned inductively-heated hot cavity catcher laser ion source at the Ion Guide Isotope Separator On-Line facility. The atomic mass of $^{95}$Ag was directly determined for the first time. [...]
