First Measurement of the $Λ_{c}^{+} \to p η^{'}$ decay

Belle Collaboration, S. X. Li, J. X. Cui +197

We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay $Λ_{c}^{+} \to p η^{'}$ with $η^{'} \to η π^{+} π^{-}$ , using a data sample corresponding to…

An optimal multiplier theorem for Grushin operators in the plane, II

Gian Maria Dall'Ara, Alessio Martini

In a previous work we proved a spectral multiplier theorem of Mihlin--Hörmander type for two-dimensional Grushin operators $- \partial_{x}^{2} - V (x) \partial_{y}^{2}$ , where $V$ is a doubl…

An optimal multiplier theorem for Grushin operators in the plane, I

Gian Maria Dall'Ara, Alessio Martini

Let $L = - \partial_{x}^{2} - V (x) \partial_{y}^{2}$ be the Grushin operator on $R^{2}$ with coefficient $V : R \to [0, \infty)$ . Under the sole assumptions that $V…

Riesz transform for a flow Laplacian on homogeneous trees

Matteo Levi, Alessio Martini, Federico Santagati +2

We prove the $L^{p}$ -boundedness, for $p \in (1, \infty)$ , of the first order Riesz transform associated to the flow Laplacian on a homogeneous tree with the canonical flow measure. T…
