According to modern physics, the mediators for all the fundamental forces of nature have spin S ≤ 2: photon for electrodynamics (S = 1), gluons for strong interactions (S = 1), bosons for the weak force (S = 1) and gravitons for the gravitational force (S = 2). Why? We show that the demand that the equations of a fundamental field are consistent in the classical limit (when quantum effects are ...

The Higgs particle is a new elementary particle predicted in the Standard Model of the elementary particle physics. It plays a special role in the theory of mass generation of quarks, leptons, and gauge bosons. In this article, theoretical issues on the Higgs mechanism are first discussed, and then experimental prospects on the Higgs particle study at the future collider experiments, LHC and IL...

Numerical modeling of machining processes is of significance in the parametric analysis and optimization of their performance. In this paper, a finite element-based model of abrasive waterjet (AWJ) cutting of a ductile material is presented with the help of an explicit, nonlinear finite element method. In this model, both solid-solid interaction and fluid-structure interaction are considered. T...

Employing the fermion unification model based on the intrinsic SU(8) symmetry of a generalized Dirac equation, we discuss the fundamental interactions under the SU(8)=SU(2)⊗SU(4) symmetry group. The physics involved can describe all fermions, the leptons (electron and neutrino), and the colored up and down quarks of the first generation in the standard model (SM) by a complex SU(8) octet of Dir...

We present a study of M(atrix) theory from a purely canonical viewpoint. In particular, we identify free particle asymptotic states of the model corresponding to the supergraviton multiplet of eleven dimensional supergravity. These states have a natural interpretation as excitations in the flat directions of the matrix model potential. Furthermore, we provide the split of the matrix model Hamil...

Elementary particle aspects using beams from accelerators and cosmic rays are compared. An important feature in high energy physics is particle identification in the final state. This technique is used to describe global features of ee-annihilations such as multiplicities and multiplicity distributions of charged hadrons and the relative fractions of pions, kaons and protons. Also the character...

We propose a Hamiltonian model that describes the interaction between a vortex line in superfluid He and the gas of elementary excitations. An equation of irreversible motion for the density operator of the vortex, regarded as a macroscopic quantum particle with a finite mass, is derived in the frame of Generalized Master Equations. This enables us to cast the effect of the coupling as a drag f...
