In a recent paper we pointed out the presence of extra fermionic degrees of freedom in a chiral gauge theory based on Connes Noncommutative Geometry. Here we propose a mechanism which provides a high mass to these mirror states, so that they decouple from low energy physics. ∗E-mail: [email protected], [email protected], [email protected], [email protected] Recently in Ref.[1] we have pointed o...

A dumbbell-shaped rigid body can be used to represent certain large spacecraft or asteroids with bimodal mass distributions. Such a dumbbell body is modeled here as two identical mass particles connected by a rigid, massless link. Equations of motion for the five degrees of freedom of the dumbbell body in a central gravitational field are obtained. The equations of motion characterize three orb...

The nite mass method, a new Lagrangian method for the numerical simulation of gas ows, is presented and analyzed. In contrast to the nite volume and the nite element method, the nite mass method is founded on a discretization of mass, not of space. Mass is subdivided into small mass packets of nite extension each of which is equipped with nitely many internal degrees of freedom. These mass pack...

To obtain the one-loop corrections to the mass of a kink by mode regularization, one may take one-half the result for the mass of a widely separated kink-antikink (or sphaleron) system, where the two bosonic zero modes count as two degrees of freedom, but the two fermionic zero modes as only one degree of freedom in the sums over modes. For a single kink, there is one bosonic zero mode degree o...

In the vacuum overlap formalism[1] of a generic chiral gauge theory, gauge symmetry is explicitly broken by the complex phase of fermion determinant. In order to restore the gauge invariance, gauge average—the integration along gauge orbit— is invoked. Then, what is required for the dynamical nature of the gauge freedom at β = ∞ (pure gauge limit) is that the global gauge symmetry is not broken...

We analyze the baryon sideward and elliptic flow from SIS (0.25 ∼ 2 AGeV) to AGS (2 ∼11.0AGeV) energies for Au + Au collisions in the relativistic transport model RBUU that includes all baryon resonances up to a mass of 2 GeV as well as string degrees of freedom for the higher mass continuum. There are two factors which dominantly determine the baryon flow at these energies: the momentum depend...

the performance of dual-layer multiple tuned mass dampers (dl-mtmd) with uniformly distributed natural frequencies is investigated. the dl-mtmd consists of one large tuned mass damper (l-tmd) and an arbitrary number of small tuned mass dampers (s-tmd). the primary structure is represented as a single degree-of-freedom system which corresponds to a specific vibration mode to be controlled in a r...
