We discuss the recent observation of f0(980) in charmless B-decays and in gluon jets which hints toward a gluonic coupling of this meson similar to η′. Further predictions on B-decays into scalar particles are presented. Charmless B decays also show a broad KK (and possibly ππ) S-wave enhancement which we relate to the 0 glueball. These gluonic mesons represent a sizable fraction of the theoret...

We report on recent progress in studying two aspects of B physics, in which penguin amplitudes play an important role: 1. Bounds on penguin pollution in B(t) → ππ constraining the CKM parameters ρ and η, and a lower bound on B → ππ improving precision in sin 2α. 2. A suggestion for measuring the photon polarization in electroweak penguin decay, B → K1(1400)γ, providing a test of the Standard Mo...

By a multitude of very important observations involving the QCD penguin, CLEO [1] has declared 1997 to be the year of the Strong Penguin. The observed size of the various modes suggest that the penguin is rather robust. The experimental observations have fueled intense theoretical activity some of which we will briefly review here. For convenience, we have divided the theoretical activity into ...

New data from the BaBar, Belle, and CLEO Collaborations on B decays to two-body charmless final states are analyzed, with the following consequences: (1) The penguin amplitude which dominates the decay B+ → π+K∗0 has a magnitude similar to that dominating B+ → π+K0. (2) The decay B+ → π+η, a good candidate for observing direct CP violation, should be detectable at present levels of sensitivity....

Non-perturbative QCD mechanisms are of fundamental importance in strong interaction physics. In particular, the flavor singlet axial anomaly leads to a gluonic pole mechanism which has been shown to explain the η ′ mass, violations of the OZI rule and more recently the proton spin. We show here that the interaction derived from the gluonic pole exchange explains the high momentum transfer behav...

We consider diagrams with up to four t-channel gluons in order to specify gluonic twist-four contributions to deep inelastic structure functions. This enables us to extend the method developed by R.K.Ellis, W.Furmanski, and R. Petronzio (EFP) [1] to the gluonic case. The method is based on low-order Feynman diagrams in combination with a dimensional analysis. It results in explicitly gauge inva...

Effects of 2- or 4-month bedrest in -6 degrees head-down tilt position with or without countermeasures on the histochemical properties of fiber phenotype and cross-sectional area (CSA) were studied in human soleus. The CSAs in slow fibers decreased approximately 32% during 4-month bedrest. This reduction was normalized after 1-month recovery. Although the reduction of percent slow fibers was no...

We investigate the role of nonperturbative quark-gluon dynamics in soft high energy processes. In order to reproduce differential and total cross sections for elastic protonproton and proton-antiproton-scattering at high energy and small momentum transfer it turns out that we need two scales, the gluonic correlation length and a confinement scale. We find a small gluonic correlation length, a ≃...
