Evidence for top quark production in nucleus-nucleus collisions
(American Physical Society, 2020-11-24)Ultrarelativistic heavy ion collisions recreate in the laboratory the thermodynamical conditions prevailing in the early universe up to 10(-6) sec, thereby allowing the study of the quark-gluon plasma (QGP), a state of ... -
Measurement of the top quark Yukawa coupling from t¯t kinematic distributions in the dilepton final state in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2020-11-30)A measurement of the Higgs boson Yukawa coupling to the top quark is presented using proton-proton collision data at root s = 13 TeV, corresponding to an integrated luminosity of 137 fb(-1), recorded with the CMS detector. ... -
Overcharging dilaton black holes in (2+1) dimensions to extremality and beyond
(World Scientific Publishing Co Pte Lt, 2020-12)We test whether static charged dilaton black holes in (2 + 1) dimensions can be turned into naked singularities by sending in test particles from infinity. We derive that overcharging is possible and generic for both ... -
Search for bottom-type, vectorlike quark pair production in a fully hadronic final state in proton-proton collisions at √s = 13 TeV
(American Physical Society, 2020-12-07)A search is described for the production of a pair of bottom-type vectorlike quarks (VLQs), each decaying into a b or (b) over bar quark and either a Higgs or a Z boson, with a mass greater than 1000 GeV. The analysis is ... -

Independently randomized symmetric policies are optimal for exchangeable stochastic teams with infinitely many decision makers
(IEEE, 2020-12-14)We study stochastic team (known also as decentralized stochastic control or identical interest stochastic game) problems with large or countably infinite number of decision makers, and characterize existence and structural ... -
Color-octet scalar decays to a gluon and an electroweak gauge boson in the Manohar-Wise model
(American Physical Society, 2020-12-28)We present one loop results for the amplitudes giving rise to couplings between a color octet scalar, a gluon, and an electroweak gauge boson. These amplitudes could signal new physics in( )gamma jet, Z jet and W jet ... -
Learning in discrete-time average-cost mean-field games
(IEEE, 2021)In this paper, we consider learning of discrete-time mean-field games under an average cost criterion. We propose a Q-iteration algorithm via Banach Fixed Point Theorem to compute the mean-field equilibrium when the model ... -

(American Physical Society, 2021-01-14)Event-by-event long-range correlations of azimuthal anisotropy Fourier coefficients ( v n ) in 8.16 TeV p Pb data, collected by the CMS experiment at the CERN Large Hadron Collider, are extracted using a subevent ... -
The variational method, backreactions, and the absorption probability in Wald type problems
(Springer, 2021-01-19)We argue that the variational method in Wald type thought experiments, involves order of magnitude problems when one imposes the fact that δM is inherently a first order quantity itself. One observes that the contribution ... -
