Dual -1 Hahn polynomials: "classical" polynomials beyond the Leonard duality
Satoshi Tsujimoto, Luc Vinet, Alexei Zhedanov
We introduce the -1 dual Hahn polynomials through an appropriate limit of the dual q-Hahn polynomials. These polynomials are orthogonal on a finite set of discrete point…
Higher Mahler measure for cyclotomic polynomials and Lehmer's question
Matilde Lalín, Kaneenika Sinha
The -higher Mahler measure of a nonzero polynomial is the integral of on the unit circle. In this note, we consider Lehmer's question (which is a long-standing o…
Measurements of branching fractions and CP asymmetries and studies of angular distributions for B to phi phi K decays
The BABAR Collaboration, J. P. Lees
We present branching fraction and CP asymmetry measurements as well as angular studies of B to phi phi K decays using 464 x 10^6 BBbar events collected by the BaBar experiment. The…
Amplitude Analysis of B0-->K+ pi- pi0 and Evidence of Direct CP Violation in B--> K* pi decays
The BABAR Collaboration, J. P. Lees
We analyze the decay B0-->K+ pi- pi0 with a sample of 454 million B Bbar events collected by the BaBar detector at the PEP-II asymmetric-energy B factory at SLAC, and extract the c…
Search for b --> u Transitions in B^{+-} --> [K^{-+} pi^{+-} pi0]_D K^{+-} Decays
The BABAR Collaboration, J. -P. Lees
We present a study of the decays B^{+-} --> D K^{+-} with D mesons reconstructed in the K+pi-pi0 or K-pi+pi0 final states, where D indicates a D0 or a anti-D0 meson. Using a sample…
Models of Quadratic Algebras Generated by Superintegrable Systems in 2D
Sarah Post
In this paper, we consider operator realizations of quadratic algebras generated by second-order superintegrable systems in 2D. At least one such realization is given for each set…
