Measurements of the pp → Wγγ and pp → Zγγ cross sections and limits on anomalous quartic gauge couplings at √s = 8 TeV
(Springer International Publishing, 2017-10-11)Measurements are presented of Wγγ and Zγγ production in proton-proton collisions. Fiducial cross sections are reported based on a data sample corresponding to an integrated luminosity of 19.4 fb−1 collected with the CMS ... -
Measurements of jet charge with dijet events in pp collisions at √s = 8 TeV
(Springer International Publishing, 2017-10-19)Jet charge is an estimator of the electric charge of a quark, antiquark, or gluon initiating a jet. It is based on the momentum-weighted sum of the electric charges of the jet constituents. Measurements of three charge ... -
Search for Higgs boson pair production in the bbττ final state in proton-proton collisions at √(s) = 8 TeV
(American Physical Society, 2017-10-20)Results are presented from a search for production of Higgs boson pairs (HH) where one boson decays to a pair of b quarks and the other to a t lepton pair. This work is based on proton-proton collision data collected by ... -
Search for associated production of dark matter with a Higgs boson decaying to bb¯ or γγ at √s = 13 TeV
(Springer International Publishing, 2017-10-26)A search for dark matter is performed looking for events with large missing transverse momentum and a Higgs boson decaying either to a pair of bottom quarks or to a pair of photons. The data from proton-proton collisions ... -
Measurement of the triple-differential dijet cross section in proton-proton collisions at √s = 8 TeV and constraints on parton distribution functions

(Springer International Publishing, 2017-11-08)Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions at root s = 8 TeV are presented. Differential cross sections are measured with data collected ... -
Measurement of charged pion, kaon, and proton production in proton-proton collisions at √s=13 TeV
(American Physical Society, 2017-12-05)Transverse momentum spectra of charged pions, kaons, and protons are measured in proton-proton collisions at root s = 13 TeV with the CMS detector at the LHC. The particles, identified via their energy loss in the silicon ... -
Eigenvalues and dynamical properties of weighted backward shifts on the space of real analytic functions
(Institute of Mathematics Polish Academy of Sciences, 2018)Usually backward shift is neither chaotic nor hypercyclic. We will show that on the space A(Omega) of real analytic functions on a connected set Omega subset of R with 0 is an element of Omega, the backward shift operator ... -
Frequently hypercyclic weighted backward shifts on spaces of real analytic functions
(TÜBİTAK, 2018)We study frequent hypercyclicity in the case of weighted backward shift operators acting on locally convex spaces of real analytic functions. We obtain certain conditions on frequent hypercyclicity and linear chaoticity ... -
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 ... -
Finite-action approximation of Markov decision processes
(Birkhäuser Basel, 2018)In this chapter, we study the finite-action approximation of optimal control policies for discrete-time Markov decision processes (MDPs) with Borel state and action spaces, under discounted and average cost criteria. One ... -

(Springer, 2018)In this chapter we study the finite-state approximation problem for computing near optimal policies for discrete-time MDPs with Borel state and action spaces, under discounted and average costs criteria. Even though existence ... -
Finite approximations in discrete-time stochastic control : quantized models and asymptotic optimality
(Birkhäuser Basel, 2018)In a unified form, this monograph presents fundamental results on the approximation of centralized and decentralized stochastic control problems, with uncountable state, measurement, and action spaces. It demonstrates how ... -
Investigation of the excited states in hidden charm hidden strange sector
(2018)In this work, we studied the radial excitations of X(4140) and like states within QCD sum rules. We chose three molecular and three diquark-antidiquark currents with the quark content cc‾ss‾ and JPC = 0++, 1++, 2++, and ... -
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 ... -
Markov-Nash equilibria in mean-field games with discounted cost
(Society for Industrial and Applied Mathematics Publications, 2018)In this paper, we consider discrete-time dynamic games of the mean-field type with a finite number $N$ of agents subject to an infinite-horizon discounted-cost optimality criterion. The state space of each agent is a Polish ... -

(Birkhäuser Basel, 2018)Control and optimization of dynamical systems in the presence of stochastic uncertainty is a mature field with a large range of applications. A comprehensive treatment of such problems can be found in excellent books and ... -
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 ... -
Prelude to part I
(Springer, 2018)Part I involves classical stochastic control problems, with a single decision maker acting repeatedly over time with its information set growing at each time stage.
