Publisher Correction: Observation of triple J/ψ meson production in proton-proton collisions
(Nature Research, 2023-12-12)Correction to: Nature Physics, published online 19 January 2023. In the version of the article initially published, the second affiliation of T. Elkafrawy was incorrect and is now shown as Ain Shams University, Cairo, Egypt ... -
Q-learning in regularized mean-field games
(Springer, 2023-03)In this paper, we introduce a regularized mean-field game and study learning of this game under an infinite-horizon discounted reward function. Regularization is introduced by adding a strongly concave regularization ... -
Quasistatic nonlinear viscoelasticity and gradient flows
(Springer Science+Business Media, 2014)We consider the equation of motion for one-dimensional nonlinear viscoelasticity of strain-rate type under the assumption that the stored-energy function is λ-convex, which allows for solid phase transformations. We formulate ... -
Radiative transitions of doubly charmed baryons in lattice QCD
(American Physical Society, 2018-12-13)We evaluate the spin-3/2→spin-1/2 electromagnetic transitions of the doubly charmed baryons on 2+1 flavor, 323×64 PACS-CS lattices with a pion mass of 156(9) MeV/c2. A relativistic heavy quark action is employed to minimize ... -
Rapidity distributions in exclusive Z plus jet and gamma plus jet events in pp collisions at root s=7 TeV
(American Physical Society, 2013-12-01)Rapidity distributions are presented for events containing either a Z boson or a photon with a single jet in proton-proton collisions produced at the CERN LHC. The data, collected with the CMS detector at s√=7 TeV, ... -
Recent results from the CMS experiment at the LHC
(EDP Sciences, 2014)Numerous studies on Jet Production, Vector Boson Production, V+Jets Production and Multi-Boson Production have been carried out by the Compact Muon Solenoid (CMS) Collaboration to test perturbative quantum chromodynamics ... -
Reconstruction and identification of τ lepton decays to hadrons and ν<inf>τ</inf> at CMS
(2016-01)This paper describes the algorithms used by the CMS experiment to reconstruct and identify τ → hadrons + ντ decays during Run 1 of the LHC. The performance of the algorithms is studied in proton-proton collisions recorded ... -
Reconstruction of decays to merged photons using end-to-end deep learning with domain continuation in the CMS detector
(American Physical Society, 2023-09-05)A novel technique based on machine learning is introduced to reconstruct the decays of highly Lorentz-boosted particles. Using an end-to-end deep learning strategy, the technique bypasses existing rule-based particle ... -
Reconstruction of signal amplitudes in the CMS electromagnetic calorimeter in the presence of overlapping proton-proton interactions
(IOP Publishing, 2020-10)A template fitting technique for reconstructing the amplitude of signals produced by the lead tungstate crystals of the CMS electromagnetic calorimeter is described. This novel approach is designed to suppress the contribution ... -
Regularized stochastic team problems
(Elsevier, 2021-03)In this paper, we introduce regularized stochastic team problems. Under mild assumptions, we prove that there exists a unique fixed point of the best response operator, where this unique fixed point is the optimal regularized ... -

Revealing the performance of bio-MOFs for adsorption-based uremic toxin separation using molecular simulations
(Elsevier, 2022-03-01)Recently, adsorption-based separation methods have been used to remove uremic toxins from the blood of chronic kidney patients. Among the porous adsorbents, metal organic frameworks (MOFs) are recognized as potential ... -
Running of the top quark mass from proton-proton collisions at √s=13 TeV
(Elsevier, 2020-04-10)The running of the top quark mass is experimentally investigated for the first time. The mass of the top quark in the modified minimal subtraction ((MS) over bar) renormalization scheme is extracted from a comparison of ... -
