Superfield equations of motion for D = 10 type IIB Dirichlet super-9-brane are obtained from the generalized action principle. The geometric equations containing fermionic superembedding equations and constraints on the generalized field strength of Abelian gauge field are separated from the proper dynamical equations and are found to contain these dynamical equations among their consequences. ...
متن کاملTau Physics: Theoretical Perspective
The leptonic decays of the τ lepton provide relevant tests on the structure of the weak currents and the universality of their couplings to the gauge bosons. The hadronic τ decay modes constitute an ideal tool for studying low–energy effects of the strong interaction in very clean conditions. Accurate determinations of the QCD coupling and the strange quark mass have been obtained with τ decay ...
متن کاملCharm physics: theoretical review
Charm physics plays a unique dual role in the modern investigations of flavor physics. Charm decay and production experiments provide valuable checks and supporting measurements for studies of CP-violation in measurements of CKM parameters in b-physics, as well as outstanding opportunities for searches for new physics. Historically, many methods of heavy quark physics have been first tested in ...
متن کاملTheoretical Physics in Crisis
Contemporary fundamental theoretical physics has been in crisis for a long time, as it cannot provide an answer to the most important question: “What is the basic structural unit of matter (space, time, energy) and how is the universe constructed of these elementary units?” The reason for this situation is explained below. Also shown, is the way to find answers to these basic questions. Crisis ...

Universal property of the information entropy in fermionic and bosonic systems. Abstract It is shown that a similar functional form S = a + b ln N holds approximately for the information entropy S as function of the number of particles N for atoms, nuclei and atomic clusters (fermionic systems) and correlated boson-atoms in a trap (bosonic systems). It is also seen that rigorous inequalities pr...
