**Abstract **:
...Through a new four components non-connex group, acting on a ten dimensional space, composed by (x,y,z,t) plus six additional dimensions we give a description of particles like photon, proton, neutron, electrons, neutrinos (e, m and t) and their anti, through the coadjoint action on the momentum space. Quantum numbers become components of the moments. Matter and antimatter are interpreted as two different movements of mass-points in this
{ z 1, z 2, z 3, z 4, z 5, z 6, x , y , z , t } space
matter movement taking place in the {z i > 0} half space and antimatter in the remnant {z i < 0} one.
The z-Symmetry : {z i ---> - z i }
which there goes with charge conjugation, becomes the definition of matter-antimatter duality. ________________________________________________________
1) Introduction.
...As pointed out by J.M.Souriau in his book [1] the Poincaré group, as a dynamic group for physics, arises a problem about the sign of the mass.
Everything starts from the Lorentz group L, whose element L is axiomaticaly defined by :
(1)
where :
(2)
The Lorentz group acts on space-time : (3)
through the action :
(4)
The matrix **G **comes from the expression of the Lorentz metric (with c=1) :
(5)
We know than the Lorentz group is composed by four components :
Ln is the neutral componant, which contains the neutral element 1, i.e. the peculiar matrix :
(6)
Ls , the second component, contains the matrix :
(7)
which reverses space.
Lt , the third component, contains the matrix :
(8)
which reverses time.
Lst , the fourth component, contains the matrix :
(9)
which reverses both space and time.
From the Lorentz group one builds the Poincaré group Gp, whose element is :
(10)
**C **is a space-time translation :
(11)
...If we use the four components of the complete Lorentz group L , (10) will be called the complete Poincaré group. As the Lotentz group, it owns four components :
- Its neutral component :
(12) (4212)
built with the neutral component Ln of the Lorentz group L.
- A second component :
(13)
built with the component Ls of the Lorentz group.
