Observation of the rare Bs0 →µ+µ− decay from the combined analysis of CMS and LHCb data
(Macmillan Publishers, 2015-06-04)The standard model of particle physics describes the fundamental particles and their interactions via the strong, electromagnetic and weak forces. It provides precise predictions for measurable quantities that can be tested ... -
Observation of the Z → ψ ℓ + ℓ − decay in pp collisions at √s = 13 TeV
(American Physical Society, 2018-10-04)This Letter presents the observation of the rare Z boson decay Z→ψ + -. Here, ψ represents contributions from direct J/ψ and ψ(2S)→J/ψX, + - is a pair of electrons or muons, and the J/ψ meson is detected via its decay to ... -

On the convergence of the nonlocal nonlinear model to the classical elasticity equation
(Elsevier, 2021-12)We consider a general class of convolution-type nonlocal wave equations modeling bidirectional propagation of nonlinear waves in a continuous medium. In the limit of vanishing nonlocality we study the behavior of solutions ... -
On the density of branching Brownian motion
(Hacettepe University, 2023-02-15)We consider a d-dimensional dyadic branching Brownian motion, and study the density of its support in the region where there is typically exponential growth of particles. Using geometric arguments and an extension of a ... -
On the existence, uniqueness, and stability of periodic waves for the fractional Benjamin–Bona–Mahony equation
(Wiley, 2022-01)The existence, uniqueness, and stability of periodic traveling waves for the fractional Benjamin–Bona–Mahony equation is considered. In our approach, we give sufficient conditions to prove a uniqueness result for the ... -
On the full dispersion Kadomtsev–Petviashvili equations for dispersive elastic waves
(Elsevier, 2022-09)Full dispersive models of water waves, such as the Whitham equation and the full dispersion Kadomtsev–Petviashvili (KP) equation, are interesting from both the physical and mathematical points of view. This paper studies ... -
On the stability of solitary wave solutions for a generalized fractional Benjamin–Bona–Mahony equation
(IOP Publishing, 2022-03-03)In this paper we establish a rigorous spectral stability analysis for solitary waves associated to a generalized fractional Benjamin-Bona-Mahony type equation. Besides the well known smooth and positive solitary wave with ... -
On the volume of the shrinking branching Brownian sausage
(The Institute of Mathematical Statistics and the Bernoulli Society, 2020)The branching Brownian sausage in R-d was defined in [4] similarly to the classical Wiener sausage, as the random subset of R-d scooped out by moving balls of fixed radius with centers following the trajectories of the ... -
On weak feller continuity properties of non-linear filters
(IEEE, 2019)Weak Feller property of controlled and control free Markov chains leads to many desirable properties. In control-free setups this leads to the existence of invariant probability measures for compact spaces and applicability ... -
Optimal survival strategy for branching Brownian motion in a Poissonian trap field
(Institut Henri Poincaré, 2019-11)We study a branching Brownian motion Z with a generic branching law, evolving in R-d, where a field of Poissonian traps is present. Each trap is a ball with constant radius. The traps are hard in the sense that the process ... -
Orbital stability of periodic standing waves for the cubic fractional nonlinear Schrödinger equation

Overcharging dilaton black holes in (2+1) dimensions to extremality and beyond
