Discriminating Z′ from anomalous trilinear gauge coupling signatures in e + e −→W + W − at ILC with polarized beams
New heavy neutral gauge bosons Z′ are predicted by many models of physics beyond the Standard Model. It is quite possible that Z′s are heavy enough to lie beyond the discovery reach of the CERN Large Hadron Colli...

Distinguishing new physics scenarios with polarized electron and positron beams
Contact-like nonstandard interactions can be revealed only through deviations of observables from the standard model (SM) predictions. We consider a number of such nonstandard scenarios, and discuss their iden...

Model-independent constraints on contact interactions from LEP2 data analysis
We derive model-independent constraints on four-fermion contact interaction-type dynamics from the published preliminary LEP2 experimental data on e + e - ...

Bhabha versus Møller scattering as a contact-interaction analyzer at a polarized Linear Collider
We discuss electron-electron contact-interaction searches in the processes \(e^+e^-\to e^+e^-\) and \(e^-e^-\to e^-e^-\) at planned Linear Colli...

Exclusiveb→s rare decays of beauty
The exclusive beauty decaysB→Kl + l − andB→K * l + l − are studied using a hadronic model based on QCD sum rules embedded in a general vector meson dominance framework. Both the short and the long distance contri...

Rare kaon decays: Theoretical overview
We briefly review the theoretical interest of rare kaon decays, emphasizing their potential as precision tests of the standard model and as signals for the existence of «new» physics.

QCD calculation of \(B \to \pi l\bar v_l \) and the matrix element |V bu|
Using QCD sum rules for a two-point function involving beauty vector currents, together with current algebra-PCAC sum rules, we estimate the hadronic matrix element in

Local duality constraints on scalar gluonium
We study O++ (gg) channel in the framework of the Gauss-Weierstrass QCD sum rules. The results of this analysis definitely support the existence of a scalar gluonium bound state. Concerning the parameters of such...

Tensor gluonium spectrum in QCD
We examine the 2++ gluonium spectrum in the framework of the Gauss-Weierstrass and Finite Energy QCD sum rules. The results of our analysis support the interpretation of the θ(1710) as a tensor glueball, but they...

QCD determination of theA 1-ρ-π system through vertex light-cone sum rules
We analyze the ρ-A 1-π system within the context of vertex light-cone sum rules, which are believed to be rigorously satisfied in QCD. It is pointed out that these sum rules provide very strong constraints on the...

Quark flavour mixing, scalar tadpole transitions and the Cabibbo angle
The origin of the Cabibbo angle is discussed in the context of semi-strong off-diagonal quark scalar tadpolesd andcu flavour transitions. Then rediagonalization of these quark flavours suggests a Cabibbo angle of...

Possible dynamical mechanism generatingSU 3 andSU 2 symmetry breaking
We discuss a dynamical mechanism forSU 3 andSU 2 symmetry breaking, based on scalar-meson-dominated tadpoles with σ-model-inspired meson and quark couplings. Meson and baryon mass differences are consistently des...
