The light hadron spectrum as computed in nonperturbative QCD is reviewed and compared to lattice data and experiment. The mixing of mesons, hybrids and glueballs is calculated in the Field Correlator Method. The strong decay mechanisms are found out in the method and compared to the known phenomenological models. The role of sea quarks (unquenched approximation) is studied analytically using ra...

We relate bulk fields in Randall-SundrumAdS5 phenomenological models to the world-volume fields of probe D7 branes in the Klebanov-Witten background of type IIB string theory. The string constructions are described by AdS5×T 1,1 in their near-horizon geometry, with T 1,1 a 5d compact internal manifold that yields N = 1 supersymmetry in the dual 4d gauge theory. The effective 5d Lagrangian descr...

The recently introduced Isolated Horizon formalism, together with a simple phenomenological model for colored black holes is used to predict a formula for the ADM mass of the solitons of the EYM system in terms of horizon properties of black holes for all values of the horizon area. In this note, this formula is tested numerically –up to a large value of the area– for spherically symmetric solu...

Physical-Technical Institute, Ural Branch of Russian Academy of Sciences, Izhevsk, Russia This work deals with the analysis of peculiarities of formation of the hyperfine fields (HFF) at the Fe nuclei in disordered alloys metalmetalloid using the ”first-principles” calculations. Some phenomenological models and justification of their usage for the interpretation of the experimental HFF distribu...

The current acceleration of the Universe is one of the most puzzling issues in theoretical physics nowadays. We are far from giving an answer in this letter to the question of its nature. Yet, with the observations we have at hand, we analyse the different patterns that the gravitational potential can show in the future. Surprisingly, gravity not only can get weaker in the near future, it can e...

In this paper, we use the time super-operator formalism in the 2-level Friedrichs model [1] to obtain a phenomenological model of mesons decay. Our approach provides a fairly good estimation of the CP symmetry violation parameter in the case of K, B and D mesons. We also propose a crucial test aimed at discriminating between the standard approach and the time super-operator approach developed t...

By employing recent data on non-mesonic decay of s-shell Λ-hypernuclei we study, within the phenomenological model of Block and Dalitz, the validity of the ∆I = 1/2 rule in the ΛN → N N process. Due to the low experimental precision, a possible violation of this rule can be neither proved nor excluded at present with sufficient accuracy: a pure ∆I = 1/2 transition amplitude is excluded at 40% c...

A few years ago (while researching embodied cognition) I focused for some time on disorders of experience, which affect representation or beliefs regarding one’s own body. One of the most fascinating and dramatic disorders was somatoparaphrenia (sometimes also astomatognosia) (Feinberg 2002). This disorder is when the patient believes that, for example, his hand is his aunt’s or wife’s hand. Or...

Foam is the natural phenomenon of bubbles that arise due to nucleation of gas in liquids. The current state of art in Computer Graphics rarely includes foam effects on large scales. In this paper we introduce a vertexbased, quasi-static equilibrium model from the field of Computational Physics as a new paradigm for foam effects. Dynamic processes like gas diffusion and bubble collapse are added...

Foam dynamics is gaining interests within Computational Fluid Dynamics and Computer Graphics. We believe that liquid foam, or froth, is the next evolution in the field of fluid dynamics. Froth is the natural phenomenon of bubbles that arise due to nucleation of gas in liquids. As the physics of foams in two dimensions is better understood this thesis begins the journey of physics-based foam dyn...
