Design of a Level-1 Long-Lived Particle Trigger in the CMS Hadron Calorimeter / Kopp, Gillian Baron (Princeton U.) ; Tully, Christopher (Princeton U.) ; Chung, Wonyong Paul (Princeton U.) ; Kennedy, Kiley Elizabeth (Princeton U.) ; Hoienko, Svitlana (Princeton U.) ; Mans, Jeremiah Michael (Minnesota U.) ; Krohn, Michael David (Minnesota U.) ; Crossman, Bryan James (Minnesota U.) ; Hiltbrand, Joshua (Baylor U.) ; Skuja, Andris (Maryland U.) et al.
The Hadron Calorimeter (HCAL) in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) was recently upgraded for Run 3 to introduce depth segmentation and online timing measurements, expanding the physics capabilities. In particular, the augmentation of the calorimeter information at the hardware trigger level enables quick identification and recording of long-lived particle decays using lower thresholds on energy-based event quantities.

Search for a new scalar decaying into new spin-1 bosons in four-lepton final states with the ATLAS detector / ATLAS Collaboration
A search is conducted for a new scalar boson $S$, with a mass distinct from that of the Higgs boson, decaying into four leptons ($\ell =$ $e$, $\mu$) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons $Z_\text{d}$: $S \rightarrow Z_\text{d}Z_\text{d} \rightarrow 4\ell$, where the $Z_\text{d}$ boson has a mass between 15 and 300 GeV, and the $S$ boson has a mass between either 30 and 115 GeV or 130 and 800 GeV.

Time Alignment of the CMS Hadron Calorimeter / Kopp, Gillian Baron (Princeton U.) ; Tully, Christopher (Princeton U.) ; Chung, Wonyong Paul (Princeton U.) ; Kennedy, Kiley Elizabeth (Princeton U.) ; Hoienko, Svitlana (Princeton U.) ; Mans, Jeremiah Michael (Minnesota U.) ; Krohn, Michael David (Minnesota U.) ; Crossman, Bryan James (Minnesota U.) ; Hiltbrand, Joshua (Baylor U.) ; Skuja, Andris (Maryland U.) et al.
The Hadron Calorimeter (HCAL) in the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) was recently upgraded for Run 3 (2022-2025) to introduce depth segmentation and online timing measurements. With increased segmentation and readout channels, the HCAL provides new timing capabilities for jets and hadronic tau decays with nearly $4\pi$ coverage and sensitivity to highly displaced decays within the calorimeter volume.

Search for diphoton resonances in the 66 to 110 GeV mass range using $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration
A search is performed for light, spin-0 bosons decaying into two photons in the 66 to 110 GeV mass range, using 140 fb$^{-1}$ of proton-proton collisions at $\sqrt{s}=13$ TeV produced by the Large Hadron Collider and collected by the ATLAS detector. [...]

Combination of measurements of the top quark mass from data collected by the ATLAS and CMS experiments at $\sqrt{s}=7$ and 8 TeV / ATLAS Collaboration
A combination of fifteen top quark mass measurements performed by the ATLAS and CMS experiments at the LHC is presented. The data sets used correspond to an integrated luminosity of up to 5 and 20$^{-1}$ of proton-proton collisions at center-of-mass energies of 7 and 8 TeV, respectively. [...]

Precise measurements of $W$- and $Z$-boson transverse momentum spectra with the ATLAS detector using $pp$ collisions at $\sqrt{s} = 5.02$ TeV and $13$ TeV / ATLAS Collaboration
This paper describes measurements of the transverse momentum spectra of $W$ and $Z$ bosons produced in proton-proton collisions at centre-of-mass energies of $\sqrt{s}=5.02$ TeV and $\sqrt{s}=13$ TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, $W \to \ell\nu$ and $Z \to \ell\ell$ ($\ell=e$ or $\mu$), and for $W$ events further separated by charge. [...]

Search for pair-produced higgsinos decaying via Higgs or $Z$ bosons to final states containing a pair of photons and a pair of $b$-jets with the ATLAS detector / ATLAS Collaboration
A search is presented for the pair production of higgsinos $\tilde{\chi}$ in gauge-mediated supersymmetry models, where the lightest neutralinos $\tilde{\chi}_1^0$ decay into a light gravitino $\tilde{G}$ either via a Higgs $h$ or $Z$ boson. The search is performed with the ATLAS detector at the Large Hadron Collider using 139 fb$^{-1}$ of proton-proton collisions at a centre-of-mass energy of $\sqrt{s}$ = 13 TeV. [...]

A Novel Timing Trigger with the CMS Hadron Calorimeter / Kopp, Gillian Baron (Princeton U.) ; Tully, Christopher (Princeton U.) ; Kennedy, Kiley Elizabeth (Princeton U.) ; Chung, Wonyong Paul (Princeton U.) ; Hoienko, Svitlana (Princeton U.) ; Mans, Jeremiah Michael (Minnesota U.) ; Krohn, Michael David (Minnesota U.) ; Crossman, Bryan James (Minnesota U.) ; Hiltbrand, Joshua (Baylor U.) ; Skuja, Andris (Maryland U.) et al.
A low-level hardware timing trigger using the Hadron Calorimeter (HCAL) in the Compact Muon Solenoid (CMS) experiment at CERN is designed and deployed for Run 3 of the Large Hadron Collider (LHC), with data taking beginning in 2022. The new Level-1 trigger relies on the Phase~1 upgrade of the HCAL, which provides greater segmentation granularity and an increased number of readout channels, and enables timing information to be used in the hardware trigger system.

Observation of electroweak production of W$^{+}$W$^{−}$ in association with jets in proton-proton collisions at $ \sqrt{s} $ = 13 TeV with the ATLAS detector / ATLAS Collaboration
A measurement of the production of $W$ bosons with opposite electric charges in association with two jets is presented based on 140 fb$^{-1}$ of data collected by the ATLAS detector in proton-proton collisions at $\sqrt{s}=13$ TeV. The analysis is sensitive to the scattering of $W$ bosons, which is of particular interest in the ATLAS physics programme as it can be used to probe the electroweak symmetry breaking mechanism of the Standard Model.

Measurement of t-channel production of single top quarks and antiquarks in pp collisions at 13 TeV using the full ATLAS Run 2 data sample / ATLAS Collaboration
The production of single top quarks and top antiquarks via the $t$-channel exchange of a virtual $W$ boson is measured in proton-proton collisions at a centre-of-mass energy of 13 TeV at the LHC using $140\,\mathrm{fb^{-1}}$ of ATLAS data. The total cross-sections are determined to be $\sigma(tq)=137^{+8}_{-8}\,\mathrm{pb}$ and $\sigma(\bar{t}q)=84^{+6}_{-5}\,\mathrm{pb}$ for top-quark and top-antiquark production, respectively. [...]
