Rapid growth of new atmospheric particles by nitric acid and ammonia condensation / Wang, Mingyi (Carnegie Mellon U.) ; Kong, Weimeng (Caltech) ; Marten, Ruby (PSI, Villigen) ; He, Xu-Cheng (Helsinki U.) ; Chen, Dexian (Carnegie Mellon U.) ; Pfeifer, Joschka (CERN) ; Heitto, Arto (Kuopio U.) ; Kontkanen, Jenni (Helsinki U.) ; Dada, Lubna (Helsinki U.) ; Kürten, Andreas (Goethe U., Frankfurt (main)) et al.
Measurements in the CLOUD chamber at CERN show that the rapid condensation of ammonia and nitric acid vapours could be important for the formation and survival of new particles in wintertime urban conditions, contributing to urban smog..

New particle formation from isoprene under upper-tropospheric conditions / Shen, Jiali (Helsinki U.) ; Russell, Douglas M (Frankfurt U., FIAS) ; DeVivo, Jenna (Carnegie Mellon U.) ; Kunkler, Felix (Mainz, Max Planck Inst.) ; Baalbaki, Rima (Helsinki U.) ; Mentler, Bernhard (Innsbruck U.) ; Scholz, Wiebke (Innsbruck U.) ; Yu, Wenjuan (Helsinki U.) ; Caudillo-Plath, Lucía (Frankfurt U., FIAS) ; Sommer, Eva (CERN ; Vienna U.) et al.
Abstract Aircraft observations have revealed ubiquitous new particle formation in the tropical upper troposphere over the Amazon1,2 and the Atlantic and Pacific oceans3,4. Although the vapours involved remain unknown, recent satellite observations have revealed surprisingly high night-time isoprene mixing ratios of up to 1 part per billion by volume (ppbv) in the tropical upper troposphere5.

Synergistic HNO$_{3}$–H$_{2}$SO$_{4}$–NH$_{3}$ upper tropospheric particle formation / Wang, Mingyi ; Xiao, Mao ; Bertozzi, Barbara ; Marie, Guillaume ; Rörup, Birte ; Schulze, Benjamin ; Bardakov, Roman ; He, Xu-Cheng ; Shen, Jiali ; Scholz, Wiebke et al.
New particle formation in the upper free troposphere is a major global source of cloud condensation nuclei (CCN). However, the precursor vapours that drive the process are not well understood. [...]

Search for central exclusive production of top quark pairs in proton-proton collisions at $ \sqrt{s} $ = 13 TeV with tagged protons / CMS Collaboration
A search for the central exclusive production of top quark-antiquark pairs ($ \mathrm{t} \bar{\mathrm{t}} $) is performed for the first time using proton-tagged events in proton-proton collisions at the LHC at a centre-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 29.4 fb$ ^{-1} $. [...]

Search for high-mass exclusive $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions at $ \sqrt{s}= $ 13 TeV / CMS Collaboration
A search is performed for exclusive high-mass $ \gamma\gamma \to \mathrm{W}\mathrm{W} $ and $ \gamma\gamma \to \mathrm{Z}\mathrm{Z} $ production in proton-proton collisions using intact forward protons reconstructed in near-beam detectors, with both weak bosons decaying into boosted and merged jets. The analysis is based on a sample of proton-proton collisions collected by the CMS and TOTEM experiments at $ \sqrt{s}= $ 13 TeV, corresponding to an integrated luminosity of 100 fb$ ^{-1} $. [...]

Search for CP violation in $ \mathrm{D^0}\to\mathrm{K^0_S}\mathrm{K^0_S} $ decays in proton-proton collisions at $ \sqrt{s} = $ 13 TeV / CMS Collaboration
A search is reported for charge-parity CP violation in $ \mathrm{D^0}\to\mathrm{K^0_S}\mathrm{K^0_S} $ decays, using data collected in proton-proton collisions at $ \sqrt{s} = $ 13 TeV recorded by the CMS experiment in 2018. The analysis uses a dedicated data set that corresponds to an integrated luminosity of 41.6 fb$ ^{-1} $, which consists of about 10 billion events containing a pair of b hadrons, nearly all of which decay to charm hadrons.

Search for dark QCD with emerging jets in proton-proton collisions at $\sqrt{s}$ = 13 TeV / CMS Collaboration
A search for ``emerging jets'' produced in proton-proton collisions at a center-of-mass energy of 13 TeV is performed using data collected by the CMS experiment corresponding to an integrated luminosity of 138 fb$ ^{-1} $. This search examines a hypothetical dark quantum chromodynamics (QCD) sector that couples to the standard model (SM) through a scalar mediator. [...]

Search for heavy neutral leptons in final states with electrons, muons, and hadronically decaying tau leptons in proton-proton collisions at $ \sqrt{s} $ = 13 TeV / CMS Collaboration
A search for heavy neutral leptons (HNLs) of Majorana or Dirac type using proton-proton collision data at $ \sqrt{s} = $ 13 TeV is presented. The data were collected by the CMS experiment at the CERN LHC and correspond to an integrated luminosity of 138 fb$ ^{-1} $. [...]

A search for long-lived heavy neutrinos (N) in the decays of B mesons produced in proton-proton collisions at $ \sqrt{s} = $ 13 TeV is presented. The data sample corresponds to an integrated luminosity of 41.6 fb$ ^{-1} $ collected in 2018 by the CMS experiment at the CERN LHC, using a dedicated data stream that enhances the number of recorded events containing B mesons.

The CMS Statistical Analysis and Combination Tool: Combine / CMS Collaboration
This paper describes the Combine software package used for statistical analyses by the CMS Collaboration. The package, originally designed to perform searches for a Higgs boson and the combined analysis of those searches, has evolved to become the statistical analysis tool presently used in the majority of measurements and searches performed by the CMS Collaboration.
