More on the finite size mass shift formula for stable particles

چکیده
The next to leading order (NLO) contribution of the generalized finite size mass shift formula for an interacting two stable particle system in a periodic L3 box is discriminated with maintaining its model independent structure and validity to all orders in perturbation theory. The influence of the NLO contribution is examined for the nucleon mass shift in the realistic nucleon-pion system.

On the finite size mass shift formula for stable particles
Lüscher’s finite size mass shift formula in a periodic finite volume, involving forward scattering amplitudes in the infinite volume, is revisited for the two stable distinguishable particle system. The generalized mass shift formulae for the boson and fermion are derived in the boson-boson and fermion-boson systems, respectively. The nucleon mass shift formula is given in the nucleon-pion syst...
متن کاملThe new implicit finite difference scheme for two-sided space-time fractional partial differential equation
Fractional order partial differential equations are generalizations of classical partial differential equations. Increasingly, these models are used in applications such as fluid flow, finance and others. In this paper we examine some practical numerical methods to solve a class of initial- boundary value fractional partial differential equations with variable coefficients on a finite domain. S...
متن کاملSpectrum of three-body bound States in a finite volume.
The spectrum of a bound state of three identical particles with a mass m in a finite cubic box is studied. It is shown that in the unitary limit, the energy shift of a shallow bound state is given by ΔE=c(κ^{2}/m)(κL)^{-3/2}|A|^{2}exp(-2κL/sqrt[3]), where κ is the bound-state momentum, L is the box size, |A|^{2} denotes the three-body analog of the asymptotic normalization coefficient of the bo...
متن کاملRummukainen-Gottlieb’s formula on two-particle system with different mass
Lüscher established a non-perturbative formula to extract the elastic scattering phases from twoparticle energy spectrum in a torus using lattice simulations. Rummukainen and Gottlieb further extend it to the moving frame, which is devoted to the system of two identical particles. In this work, we generalize Rummukainen-Gottlieb’s formula to the generic two-particle system where two particles a...
متن کاملBioreactor Scale-up for Water-Gas Shift Reaction
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
