4 Conclusion
We introduced a simple new form of the t-dependence of GPDs. It satisfies the conditions
of the non-factorization, condition on the power of (1 − x) n in the exponential form of the
t-dependence. With this simple form we obtained a good description of the proton electromagnetic
Sachs form factors. Using the isotopic invariance we obtained good descriptions
of the neutron Sachs form factors without changing any parameters.
On the basis of our results we calculated the contribution of the u and d quarks to the
gravitational form factor of the nucleons. The obtained transverse asymmetry determined
by the contribution of the u-quark distribution. The relative asymmetry of the sum of
the u and d quarks contributions is very small at small x and it is large at large x.
