نویسنده
چکیده
Mach's definition of mass is completed and simplified. An operative definition of inertial reference frame is proposed. The second and the third law of dynamics are stated for an isolated pair of material points at rest, in a form which does not involve the concept of force. By means of the third law of dynamics, it is proved that the ratio of two masses is independent of the choice of the reference material point and can be measured directly. This proof completes Mach's definition of mass. Then, force is defined as the product of mass and acceleration. Finally, the definitions of mass and force are extended to the framework of special relativity.

The mass spectrum of cb̄ meson is investigated with an effective quark-antiquark potential of the form −αc r + A r with ν varying from 0.5 to 2.0. The S and P-wave masses, pseudoscalar decay constant, weak decay partial widths in spectator model and the lifetime of Bc meson are computed. The properties calculated here are found to be in good agreement with other theoretical and experimental valu...

If recent results of the PVLAS collaboration proved to be correct, some alternative to the traditional axion models are needed. We present one of the simplest possible modifications of axion paradigm, which explains the results of PVLAS experiment, while avoiding all the astrophysical and cosmological restrictions. We also mention other possible models that possess similar effects.
