CEPC Technical Design Report: Accelerator / CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). [...]

The polarization of $\Lambda$ and $\bar{\Lambda}$ hyperons along the beam direction has been measured relative to the second and third harmonic event planes in isobar Ru+Ru and Zr+Zr collisions at $\sqrt{s_{NN}}$ = 200 GeV. This is the first experimental evidence of the hyperon polarization by the triangular flow originating from the initial density fluctuations. [...]

Fully heavy tetraquark states and their evidences in LHC observations / liu, Ming-Sheng (Hunan Normal U. ; Hunan, LDQSQC ; SICQEA, Changsha) ; Liu, Feng-Xiao (Hunan Normal U. ; Hunan, LDQSQC ; SICQEA, Changsha) ; Zhong, Xian-Hui (Hunan Normal U. ; Hunan, LDQSQC ; SICQEA, Changsha) ; Zhao, Qiang (Beijing, Inst. High Energy Phys. ; North China Electric Power U., Beijing ; Beijing, GUCAS ; SICQEA, Changsha)
Stimulated by the exciting progress on the observations of the fully-charmed tetraquarks at LHC, we carry out a combined analysis of the mass spectra and fall-apart decays of the $1S$-, $2S$-, and $1P$-wave $cc\bar{c}\bar{c}$ states in a nonrelativistic quark model (NRQM). It is found that the $X(6600)$ structure observed in the di-$J/\psi$ invariant mass spectrum can be explained by the $1S$-wave state $T_{(4c)0^{++}}(6550)$. [...]

Measurement of single-diffractive dijet production in proton-proton collisions at $\sqrt{s} =$ 8 TeV with the CMS and TOTEM experiments / CMS and TOTEM Collaborations
Measurements are presented of the single-diffractive dijet cross section and the diffractive cross section as a function of the proton fractional momentum loss $\xi$ and the four-momentum transfer squared $t$. Both processes ${\mathrm{p}}{\mathrm{p}} \to {\mathrm{p}}\mathrm{X}$ and ${\mathrm{p}}{\mathrm{p}} \to \mathrm{X}{\mathrm{p}}$, ie with the proton scattering to either side of the interaction point, are measured, where $\mathrm{X}$ includes at least two jets; the results of the two processes are averaged [...]

Studies of charm quark diffusion inside jets using PbPb and pp collisions at $\sqrt{s_\mathrm{NN}} =$ 5.02 TeV / CMS Collaboration
The first study of charm quark diffusion with respect to the jet axis in heavy ion collisions is presented. The measurement is performed using jets with ${p_{\mathrm{T}}^{\text{jet}}} > $ 60 GeV/$c$ and ${\mathrm{D^0}}$ mesons with ${p_{\mathrm{T}}^{\text{D}}} > $ 4 GeV/$c$ in lead-lead (PbPb) and proton-proton (pp) collisions at a nucleon-nucleon center-of-mass energy of $ {\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV, recorded by the CMS detector at the LHC.

Bose-Einstein correlations of charged hadrons in proton-proton collisions at $\sqrt{s} =$ 13 TeV / CMS Collaboration
Bose-Einstein correlations of charged hadrons are measured over a broad multiplicity range, from a few particles up to about 250 reconstructed charged hadrons in proton-proton collisions at $\sqrt{s} =$ 13 TeV. The results are based on data collected using the CMS detector at the LHC during runs with a special low-pileup configuration. [...]

Strange hadron production in $pp$ and $p$Pb collisions at ${\sqrt {\smash [b]{s_{_{\mathrm {NN}}}}}} = $ 5.02 TeV / CMS Collaboration
The transverse momentum (${p_{\mathrm{T}}}$) distributions of $\Lambda$, $ \Xi^{-}$, and $\Omega^{-}$ baryons, their antiparticles, and ${\mathrm{K^0_S}}$ mesons are measured in proton-proton (pp) and proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV over a broad rapidity range. The data, corresponding to integrated luminosities of 40.2 nb$^{-1}$ and 15.6 $\mu$b$^{-1}$ for pp and pPb collisions, respectively, were collected by the CMS experiment. [...]

Measurements of triple-differential cross sections for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} = $ 8 TeV / CMS Collaboration
Measurements are presented of the triple-differential cross section for inclusive isolated-photon+jet events in pp collisions at $\sqrt{s} = $ 8 TeV as a function of photon transverse momentum (${p_{\mathrm{T}}^{\gamma}}$), photon pseudorapidity (${\eta^{\gamma}}$), and jet pseudorapidity (${\eta^{\text{jet}}}$). The data correspond to an integrated luminosity of 19.7 fb$^{-1}$ that probe a broad range of the available phase space, for $ | {\eta^{\gamma}} | < $ 1.44 and 1.57 $ < | {\eta^{\gamma}} | < $ 2.50, $ | {\eta^{\text{jet}}} | < $ 2.5, 40 $ < {p_{\mathrm{T}}^{\gamma}} < $ 1000 GeV, and jet transverse momentum, $p_{\mathrm{T}}^{\text{jet}}$, $ > $ 25 GeV.

Search for light pseudoscalar boson pairs produced from decays of the 125 GeV Higgs boson in final states with two muons and two nearby tracks in pp collisions at $\sqrt{s} = $ 13 TeV / CMS Collaboration
A search is presented for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the pseudoscalars decays to a pair of tau leptons, and the other one either into a pair of tau leptons or muons. [...]

Measurements of the top quark polarization and top quark pair ($\mathrm{t\bar{t}}$) spin correlations are presented using events containing two oppositely charged leptons ($\mathrm{e^{+}}\mathrm{e^{-}}$ , $\mathrm{e}^{\pm}\mu^{\mp}$ , or $\mu\mu$) produced in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.9 fb$^{-1}$. [...]
