Angular analysis of the decay B + → K + μ + μ − in proton-proton collisions at √s =8 TeV
(American Physical Society, 2018-12-01)The angular distribution of the flavor-changing neutral current decay B+→K+μ+μ- is studied in proton-proton collisions at a center-of-mass energy of 8 TeV. The analysis is based on data collected with the CMS detector at ... -
Angular analysis of the decay B + → K ∗ (892) +µ +µ − in proton-proton collisions at √s = 8 TeV
(Springer, 2021-01-14)Angular distributions of the decay B+→ K∗(892)+μ+μ− are studied using events collected with the CMS detector in s = 8 TeV proton-proton collisions at the LHC, corresponding to an integrated luminosity of 20.0 fb−1. The ... -
Angular analysis of the decay B0→K*0μ+μ- from pp collisions at s=8 TeV
(Elsevier, 2016-02-10)The angular distributions and the differential branching fraction of the decay B0→K⁎(892)0μ+μ− are studied using data corresponding to an integrated luminosity of 20.5 fb−1 collected with the CMS detector at the LHC in pp ... -
Angular coefficients of Z bosons produced in pp collisions at s=8 TeV and decaying to μ+μ- as a function of transverse momentum and rapidity
(Elsevier, 2015-11-12)Measurements of the five most significant angular coefficients, A0 through A4, for Z bosons produced in pp collisions at View the MathML source and decaying to μ+μ− are presented as a function of the transverse momentum ... -
An approach to nonlinear viscoelasticity via metric gradient flows
(SIAM, 2014)We formulate quasistatic nonlinear finite-strain viscoelasticity of rate type as a gradient system. Our focus is on nonlinear dissipation functionals and distances that are related to metrics on weak diffeomorphisms and ... -
Approximate markov-nash equilibria for discrete-time risk-sensitive mean-field games
(Informs, 2020-11)In this paper, we study a class of discrete-time mean-field games under the infinite-horizon risk-sensitive optimality criterion. Risk sensitivity is introduced for each agent (player) via an exponential utility function. ... -
Approximate nash equilibria in partially observed stochastic games with mean-field interactions
(Informs, 2019-08)Establishing the existence of Nash equilibria for partially observed stochastic dynamic games is known to be quite challenging, with the difficulties stemming from the noisy nature of the measurements available to individual ... -
Approximation by special values of Dirichlet series
(American Mathematical Society, 2020)The classification of the irreducible unitary representations of the stabilizer of the horocycles of a homogeneous tree of finite degree is well-known. In this article we use these stabilizers to form an Olshanski pair and ... -
Approximations for constrained Markov decision problems
(Springer, 2018)This chapter studies the finite-state approximation of a discrete-time constrained Markov decision process with compact state space, under the discounted and average cost criteria. Using the linear programming formulation ... -
Approximations for partially observed Markov decision processes
(Birkhäuser Basel, 2018)This chapter studies the finite-model approximation of discrete-time partially observed Markov decision process. We will find that by performing the standard reduction method, where one transforms a partially observed model ... -
Asymptotic optimality of finite model approximations for partially observed markov decision processes with discounted cost
(IEEE, 2020-01)We consider finite model approximations of discrete-time partially observed Markov decision processes (POMDPs) under the discounted cost criterion. After converting the original partially observed stochastic control problem ... -
Asymptotic optimality of finite models for witsenhausen’s counterexample and beyond
(Birkhäuser Basel, 2018)In this chapter, we study the approximation of Witsenhausen’s counterexample and the Gaussian relay channel problem by using the results of the previous chapter. In particular, our goal is to establish that finite models ... -
Author Correction: A portrait of the Higgs boson by the CMS experiment ten years after the discovery
(Nature Research, 2022-11-02)In the version of this article initially published, CMS Collaboration author names, affiliations and acknowledgements were omitted and have now been included in the HTML and PDF versions of the article. -
Axial-tensor meson family at T≠0
(Springer Nature, 2020-10-12)The mass and decay constants of rho(2), omega(2) and a missing member in the 2(--) nonet along with their first excited states are analyzed by the Thermal QCD sum rules approach, including QCD condensates up to dimension ... -
Azimuthal anisotropy of charged particles with transverse momentum up to 100 GeV/c in PbPb collisions at √sNN= 5.02 TeV
(Elsevier, 2018-01)The Fourier coefficients v(2) and v(3) characterizing the anisotropy of the azimuthal distribution of charged particles produced in PbPb collisions at root S-NN = 5.02 TeV are measured with data collected by the CMS ... -
Azimuthal anisotropy of dijet events in PbPb collisions at √sNN=5.02 TeV
(Springer, 2023-07-17)The path-length dependent parton energy loss within the dense partonic medium created in lead-lead collisions at a nucleon-nucleon center-of-mass energy of root s(NN) = 5.02TeV is studied by determining the azimuthal ... -
Azimuthal correlations within exclusive dijets with large momentum transfer in photon-lead collisions
(American Physical Society, 2023-08-04)The structure of nucleons is multidimensional and depends on the transverse momenta, spatial geometry, and polarization of the constituent partons. Such a structure can be studied using high-energy photons produced in ... -
Azimuthal decorrelation of jets widely separated in rapidity in pp collisions at s√=7s=7 TeV
(Springer International Publishing, 2018)The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at s√=7s=7 TeV. The ... -
Azimuthal separation in nearly back-to-back jet topologies in inclusive 2- and 3-jet events in pp collisions at s√=13TeV

B → T transition form factors in light-cone sum rules
(American Physical Society, 2019-11-11)We present a new calculation of the semileptonic tree-level and flavor-changing neutral current form factors describing B-meson transitions to tensor mesons T ¼ D2, K2, a2, f2 (JP ¼ 2þ). We employ the QCD light-cone sum ...
