Heavy quarks, Higgs scalars, B-mesons and Gauge interactions at high energy

Objective



In this project, the participants will extend their previous results, to find compact theoretical expressions for one loop radiative corrections of Electroweak theory to different physical observables at LEP and at future colliders. Comparing them with experimental data one can, in principle, obtain not only the bounds on the top quark and Higgs boson masses (on mt and Mh) but also understand the status of Electroweak theory.

This project aims at understanding the connection of new experimental data on mt with information which follows (independently of Mh value) from theory of B-meson decays and B degree - `B degree oscillations. For that aim, the theory of B-decays, in particular to multihadron final states, was revised. Non-perturbative QCD wave function of B-meson will be used and also small QCD corrections will be considered. About 20% of the so-called internal inclusive non-leptonic B-decays into heavy mesons and in baryon pairs (previously lost) were found. In this approach the participants plan to calculate all decay main branchings and distributions. In connection with these problems a new model of unification approach (so-called anti-grand unification) is being developed and the phase transitions with a change to the internal symmetry are being considered. Values of gauge coupling (i.e. of the fine structure) constants will be studied in the vicinity of the multicritical point. The role of Higgs scalars, of monopoles, strings and fermions in this new approach will also be investigated.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
