We study the exclusive decays of B meson into P-wave charmonium states χcJ(J = 0, 1) within QCD factorization approach and find that for B → χc1K decay, the factorization breaks down due to logarithmic divergences arising from nonfactorizable spectator interactions even at twist-2 order, and the decay rate is too small to accommodate the data, and that for B → χc0K decay, there are infrared div...

We discuss the transition from quasi-circular inspiral to plunge of a system of two nonrotating black holes of masses m1 and m2 in the extreme mass ratio limit m1m2 ≪ (m1+m2). In the spirit of the Effective One Body (EOB) approach to the general relativistic dynamics of binary systems, the dynamics of the two black hole system is represented in terms of an effective particle of mass μ ≡ m1m2/(m...

Coordination and harmony between different departments of a company can be an important factor in achieving competitive advantage if the company corrects alignment between strategies of different departments. This paper presents an integrated decision model based on recent advances of geometric programming technique. The demand of a product considers as a power function of factors such as produ...

The general equation from previous work is specialized to a linear potential V (r) = −a + F r acting in the space of spherically symmetric S wave functions. The fine and hyperfine interaction creates then a 1 r -dependence in the effective potential energy equation and a position dependent mass m̃(r) in the effective kinetic energy of the associated Schrödinger equation. The results are compared...

We establish a solution to the Monge problem in N , with an asymmetric, strictly convex norm cost function, when the initial measure is absolutely continuous. We focus on the strategy, based on disintegration of measures, initially proposed by Sudakov. As known, there is a gap to fill. The missing step is completed when the unit ball is strictly convex, but not necessarily differentiable nor un...

Consider the problem of partitioning n nonnegative numbers into p parts, where part i can be assigned ni numbers with ni lying in a given range. The goal is to maximize a Schur convex function F whose i th argument is the sum of numbers assigned to part i . The shape of a partition is the vector consisting of the sizes of its parts, further, a shape (without referring to a particular partition)...

The paper deals with affine selections of affine (both convex and concave) multifunctions acting between finite-dimensional real normed spaces. It is proved that each affine multifunction with compact values possesses an exhaustive family of affine selections and, consequently, can be represented by its affine selections. Moreover, a convex multifunction with compact values possesses an exhaust...

We study the problem of aggregation of estimators when the estimators are not independent of the data used for aggregation and no sample splitting is allowed. If the estimators are deterministic vectors, it is well known that the minimax rate of aggregation is of order log(M), where M is the number of estimators to aggregate. It is proved that for affine estimators, the minimax rate of aggregat...

We study a continuous version of the capacity and flow assignment problem (CFA) where the design cost is combined with an average delay measure to yield a non convex objective function coupled with multicommodity flow constraints. A separable convexification of each arc cost function is proposed to obtain approximate feasible solutions within easily computable gaps from optimality. On the other...
