CMS RPC performance and operation in LHC Run 3 / CMS Collaboration
The CMS experiment has collected more than 180 fb$^{-1}$ of proton-proton collision data at a 13.6 TeV center-of-mass energy in Run 3 data taking (2022, 2023 and 2024). The CMS RPC system faces the challenge of the LHC delivered instantaneous luminosity of up to 2 x 10$^{34}$ cm$^{-2}$s$^{-1}$, providing redundant information for robust muon triggering, reconstruction and identification.

Modeling charged-particle multiplicity distributions at LHC / Radi, Amr (Sultan Qaboos U. ; Ain Shams U., Cairo)
With many applications in high-energy physics, Deep Learning or Deep Neural Network (DNN) has become noticeable and practical in recent years. In this article, a new technique is presented for modeling the charged particles multiplicity distribution Pn of Proton-Proton (PP) collisions using an efficient DNN model. [...]

Search for third-generation scalar leptoquarks and heavy right-handed neutrinos in final states with two tau leptons and two jets in proton-proton collisions at $ \sqrt{s}=13 $ TeV / CMS Collaboration
A search is performed for third-generation scalar leptoquarks and heavy right-handed neutrinos in events containing one electron or muon, one hadronically decaying tau lepton, and at least two jets, using a sqrt(s) = 13 TeV pp collision data sample corresponding to an integrated luminosity of 12.9 inverse femtobarns collected with the CMS detector at the LHC in 2016. The number of observed events is found to be in agreement with the standard model prediction. [...]

Measurement of double-differential cross sections for top quark pair production in pp collisions at $\sqrt{s} = $ 8 TeV and impact on parton distribution functions / CMS Collaboration
Normalized double-differential cross sections for top quark pair ($ \mathrm{ t \bar{t} } $) production are measured in pp collisions at a centre-of-mass energy of 8 TeV with the CMS experiment at the LHC. The analyzed data correspond to an integrated luminosity of 19.7 fb$^{-1}$. [...]

Search for associated production of a Z boson with a single top quark and for tZ flavour-changing interactions in pp collisions at $ \sqrt{s} = $ 8 TeV / CMS Collaboration
A search for the production of a single top quark in association with a Z boson is presented, both to identify the expected standard model process and to search for flavour-changing neutral current interactions. The data sample corresponds to an integrated luminosity of 19.7 fb$^{-1}$ recorded by the CMS experiment at the LHC in proton-proton collisions at $ \sqrt{s} = $ 8 TeV. [...]

Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/$c$ in PbPb collisions at $\sqrt{ s_{\mathrm{NN}} } = $ 5.02 TeV / CMS Collaboration
The Fourier coefficients $v_2$ and $v_3$ characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at $\sqrt{ s_{\mathrm{NN}} } = $ 5.02 TeV are measured with data collected by the CMS experiment. The measurements cover a broad transverse momentum range, $p_{\mathrm{T}}= $ 1-100 GeV/$c$. [...]

Mechanical stability of the CMS strip tracker measured with a laser alignment system / CMS Collaboration
The CMS tracker consists of 206 m$^2$ of silicon strip sensors assembled on carbon fibre composite structures and is designed for operation in the temperature range from $-25$ to $+25^\circ$C. The mechanical stability of tracker components during physics operation was monitored with a few $\mu$m resolution using a dedicated laser alignment system as well as particle tracks from cosmic rays and hadron-hadron collisions.
