f4201 Geometrization of matter and antimatter through coadjoint action of a group on its momentum space. 1 : Charges as additional scalar components of the momentum of a group acting on a 10d-space

Geometrical definition of antimatter.

Jean-Pierre Petit & Pierre Midy

**Observatoire de Marseille ** ---

**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.
