We calculate the cross-section for the thermal n + p! d+ process in chiral perturbation theory to next-to-next-to-leading order using heavy-fermion formalism. The exchange current correction is found to be (4:5 0:3) % in amplitude and the chiral perturbation at one-loop order gives the cross section np th = (334 2) mb which is in agreement with the experimental value (334:2 0:5) mb. Together wi...

The authors regret that there is an error in the Materials and Methods section of their paper. In the section ‘‘2.4 Outcome measures’’, in the subsection on STESS: ‘‘. . . STESS is a prognostic score based on four outcome predictors: age (<65 years = 0, 65 years = 100. Here 1 needs to be replaced by 2. So the correct text is as follows: ‘‘. . . STESS is a prognostic score based on four outcome ...

The stability condition or non-degeneracy property means that the interior angles of all elements have to be bounded uniformly away from zero. Non-degeneracy is essential, for example, for the approximation properties of finite element spaces and the convergence behavior of multigrid and multilevel algorithms. Rosenberg and Stenger [1] showed the non-degeneracy property for LE-bisection: if α0 ...

Cross section of the formation of mesic molecular complex (MMC) in the reactions (tp.)F+ (D2).;K; -+ [(dtp.)iVdee].,K, is calculated at low energies (E < 100 K). We assume the Breit-Wigner energy dependence of the cross section. In calculating the entrance widths the electron screening and various orbital moments of the incident tp.-atom were taken into account. Owing to anharmonic corrections ...

The unintegrated gluon density in the photon is determined, using the Kimber-MartinRyskin prescription . In addition, a model of the unintegrated gluon is proposed, based on the saturation model extended to the large-x region. These gluon densities are applied to obtain cross sections for charm and bottom production in γp and γγ collisions using the kt factorization approach. We investigate bot...

We study the correlation of photon and charged lepton pseudorapidities, η(γ) and η(ℓ), ℓ = e, µ, in p¯ p → W ± γ + X → ℓ ± p / T γ + X at the Tevatron. In the Standard Model, the ∆η(γ, ℓ) = η(γ) − η(ℓ) differential cross section is found to exhibit a pronounced dip at ∆η(γ, ℓ) ≈ ∓0.4, which originates from the radiation zero present in q ¯ q ′ → W γ. The sensitivity of the ∆η(γ, ℓ) distribution...

1. A principal bundle 33(X, G) with base space X and group G is called "locally flat" if the structural group G can be reduced to a totally disconnected subgroup GiCG, or in other words: if there exists a totally disconnected subgroup GiQG, a principal bundle 33i(X, Gi) and an injection j: Soi—>33 [l ]. For instance, if a differentiable bundle 33 admits an infinitesimal connection whose curvatu...

We discuss microscopic cluster model descriptions of two solar nuclear reactions , 7 Be(p, γ) 8 B and 3 He(3 He, 2p) 4 He. The low-energy reaction cross section of 7 Be(p, γ) 8 B, which determines the high-energy solar neutrino flux, is constrained by 7 Be and 8 B observables. Our results show that a small value of the zero-energy cross section is rather unlikely. In 3 He(3 He, 2p) 4 He we stud...

In Takemura and Kuriki (1999b) we have established that the tube formula and the Euler characteristic method give identical and valid asymptotic expansion of tail probability of the maximum of Gaussian random field when the random field has finite Karhunen-Loève expansion and the index set has positive critical radius. The purpose of this paper is to show that the positiveness of the critical r...

Saving and investment are I(1) processes and generally do not cointegrate. This suggests the need for a nonstationary panel methodology to estimate the long run saving-investment association. We reconsider the Feldstein-Horioka puzzle using a mean group procedure which provides consistent estimates for nonstationary, heterogeneous panels. The resultant slope coe¢cient estimate for 12 OECD econo...
