The partial decay rate of the Z boson into bottom quarks constitutes an important decay channel. This is mainly due to the virtual presence of the top quark in the loop diagrams giving rise to correction factors which are quadratic in the top quark mass. At one-and two-loop order it turned out that the leading term in the heavy-top expansion leads to very good approximations to the exact result...

abstract background thalassemia is common in the iranian population, and it must be considered in the differential diagnosis of the microcytic hypochromic anemia. the molecular analysis of β-thalassemia is necessary for prenatal molecular diagnosis. α-thalassemia caused by loss of function of either one of the two duplicated α-globin genes or in less frequent non deletion mutations mostly locat...

Particle-in-Cell (PIC) simulation codes have wide applicability to first-principles modeling of multidimensional nonlinear plasma phenomena, including wake-field accelerators. This review addresses both finite difference and pseudo-spectral PIC algorithms, including numerical instability suppression and generalizations of the spectral field solver. INTRODUCTION AND SUMMARY Particle-in-Cell (PIC...

We present a complete calculation of the photon + 1 jet rate in e+e− annihilation up to O(ααs). Although formally of next-to-leading order in perturbation theory, this calculation contains several ingredients appropriate to a next-to-next-to-leading order calculation of jet observables. In particular, we describe a generalization of the commonly used phase space slicing method to isolate the si...
