We present results on a new operator for the investigation of stringbreaking effects in quenched SU(2)-colour QCD. The ground-state of a spatially-separated static-light meson-antimeson pair is a combination of a state with two distinct mesons, expected to dominate for large separations, and a state where the light-quarks have annihilated, which contributes at short distances. The crossover bet...

We examine the Mazur-Tate canonical height pairing defined between an abelian variety over a global field and its dual. By expressing local factors of this pairing in terms of nonarchimedean theta functions, we show in the case of global function fields that certain of these pairings are annihilated by universal norms coming from Carlitz cyclotomic extensions. Furthermore, for elliptic curves w...

This work is concerned with an extension of classical mixture theory to the case in which the mixture contains an evolving non-material surface on which the constituents may interact, as well as be created and/or annihilated. The formulation of constituent and mixture jump balance relations on/across such a non-material surface proceed by analogy with the standard "volume" or "bulk" constituent...

A bstract We discuss the Bosonic sector of a class supersymmetric non-Lorentzian five-dimensional gauge field theories with an SU(1 , 3) conformal symmetry. These actions have Lagrange multiplier which imposes novel Ω-deformed anti-self-dual constraint. Using generalised ’t Hooft ansatz we find constraint equation linearizes allowing us to construct wide explicit solutions. include finite actio...

OBJECTIVE To investigate the effect of vitrification and beta-mercaptoethanol (beta-ME) on reactive oxygen species (ROS) activity and in vitro development of oocytes vitrified before or after in vitro fertilization (IVF).

For certain negative rational numbers κ0, called singular values, and associated with the symmetric group SN on N objects, there exist homogeneous polynomials annihilated by each Dunkl operator when the parameter κ = κ0. It was shown by de Jeu, Opdam and the author (Trans. Amer. Math. Soc. 346 (1994), 237-256) that the singular values are exactly the values − n with 2 ≤ n ≤ N , m = 1, 2, . . . ...

We study how one-particle correlations transfer to manifest as two-particle correlations in the context of parametric down-conversion (PDC), a process in which a pump photon is annihilated to produce two entangled photons. We work in the polarization degree of freedom and show that for any two-qubit generation process that is both trace-preserving and entropy-nondecreasing, the concurrence C(ρ)...

Semileptonic transitions of one meson into another yield important measurements of both weak and strong dynamics. By comparing the experimentally determined decay rate to a theoretical normalization of the relevant hadron transition amplitude at one or more kinematic points, elements of the CabibboKobayashi-Maskawa (CKM) matrix are determined. Independent of the overall normalization, the shape...
