A spectral isoperimetric inequality on the n-sphere for the Robin-Laplacian with negative boundary parameter
Paolo Acampora, Antonio Celentano, Emanuele Cristoforoni +2
For every given , we study the problem of maximizing the first Robin eigenvalue of the Laplacian among convex (not necessarily smooth) sets w…
50 GeV in, nothing out: a sensitive probe of invisible and decays with NA64h
Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +54
We present the first results from a proof-of-concept search for dark sectors via invisible decays of pseudoscalar and mesons in the NA64h experiment at the CERN SPS. Our n…
A Talenti comparison result for a class of Neumann boundary value problems
Antonio Celentano, Carlo Nitsch, Cristina Trombetti
In this paper, we establish a comparison principle in terms of Lorentz norms and point-wise inequalities between a positive solution to the Poisson equation with non-homogeneou…
First constraints on the explanation of the muon anomaly from NA64- at CERN
Yu. M. Andreev, A. Antonov, D. Banerjee +58
The inclusion of an additional gauge symmetry would release the tension between the measured and the predicted value of the anomalous muon magnetic moment: this pa…
On a Serrin-type overdetermined problem
Antonio Celentano, Carlo Nitsch, Cristina Trombetti
In this paper, we prove a Serrin-type result for an elliptic system of equations, overdetermined with both Dirichlet and a generalized Neumann conditions. With this tool, we charac…
