Measurement of the inclusive semileptonic $B$ meson branching fraction in 62.8 fb$^{-1}$ of Belle II data / Belle-II Collaboration
We report a measurement of the branching fraction of inclusive semileptonic $B$ meson decays $B\to X_c\ell\nu\ell$ in $\Upsilon(4S)\to B\bar B$~data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+e^-$ collider and corresponding to 62.8 fb$^{-1}$ of integrated luminosity.

Exclusive $B \to X_u \ell \nu_\ell$ Decays with Hadronic Full-event-interpretation Tagging in 62.8 fb$^{-1}$ of Belle II Data / Belle-II Collaboration
We present a reconstruction in early data of the semileptonic decay $B^+ \to \pi^0 \ell^+ \nu_\ell$, and first results of a reconstruction of the decays $B^+ \to \rho^0 \ell^+ \nu_\ell$ and $B^0 \to \rho^- \ell^+ \nu_\ell$ in a sample corresponding to 62.8 fb$^{-1}$ of Belle II data using hadronic $B$-tagging via the full-event-interpretation algorithm.

Measurements of branching fractions and CP-violating charge asymmetries in multibody charmless $B$ decays reconstructed in 2019-2020 Belle II data / Belle-II Collaboration
We report on measurements of branching fractions ($\mathcal{B}$) and CP-violating charge asymmetries ($\mathcal{A}_{\rm CP}$) of multibody charmless $B$ decays reconstructed by the Belle II experiment at the SuperKEKB electron-positron collider. [...]

Search for Darkonium in $e^+e^-$ Collisions / BABAR Collaboration
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In particular, the existence of dark matter bound states (darkonia) remains to be investigated. [...]

The Belle II Physics Book / Belle-II Collaboration
We present the physics program of the Belle II experiment, located on the intensity frontier SuperKEKB e+e- collider. Belle II collected its first collisions in 2018, and is expected to operate for the next decade. [...]

Measurement of the mass difference between top quark and antiquark in pp collisions at $\sqrt{s} = 8$ TeV / CMS Collaboration
The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Delta m[t] = m[t] - m[t-bar]) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state.

The CMS trigger system / CMS Collaboration
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. [...]

Measurement of electroweak production of a W boson and two forward jets in proton-proton collisions at $ \sqrt{s} = $ 8 TeV / CMS Collaboration
A measurement is presented of the cross section for the electroweak production of a W boson in association with two jets in proton-proton collisions at a center-of-mass energy of 8 TeV. The data set was collected with the CMS detector and corresponds to an integrated luminosity of 19.3 fb$^{-1}$. [...]

Search for lepton flavour violating decays of the Higgs boson to $\mathrm{ e }\tau$ and $\mathrm{ e }\mu$ in proton-proton collisions at $\sqrt{s}= $ 8 TeV / CMS Collaboration
A direct search for lepton flavour violating decays of the Higgs boson (H) in the $\mathrm{ H } \to \mathrm{ e } \tau$ and $\mathrm{ H } \to \mathrm{ e } \mu$ channels is described. The data sample used in the search was collected in proton-proton collisions at $\sqrt{s}= $ 8 TeV with the CMS detector at the LHC and corresponds to an integrated luminosity of 19.7 fb$^{-1}$.

Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV / CMS Collaboration
Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are presented. The corrections as a function of pseudorapidity $\eta$ and transverse momentum $p_{\mathrm{T}}$ are extracted from data and simulated events combining several channels and methods. [...]
