2 Mexican Particle Accelerator Community ( C omunidad M exicana de A celeradores de P articulas ) In 2015, the Mexican Particle Accelerator community was created. Its main objective is to develop the science and technology of particle accelerators in Mexico and train human resources. Goals: Stablish and maintain collaborations with international labs: CERN, JLAB, LNLS, Etc. Developping own projects in Mexico. CMAP members cover different aspects of the accelerators science and technology.

3 CMAP MEMBERS • Accelerator physics spans over many areas and subjects. Each member works in a different subject.

5 Name: Marco Alan Valdivia Degree: Master in Physics Affiliations: University of Guanajuato/CERN Institutions where develops his research: CERN alan.valdivia@cern.ch Working topic: EffectTowards a monochoromatizaition scheme for direct Higgs productions: Direct Higgs production in e+e- collisions at the FCC is of interest if the centre-of-mass energy spread can be reduced by at least an order of magnitude. A mono- chromatization scheme, to accomplish this, can be realized with horizontal dispersion of opposite sign for the two colliding beams at the interaction point (IP). Effect of Beamstrahlung on Bunch Length and Emittance in Future Circular e+e− Colliders: In future circular e+e- colliders, beamstrahlung may limit the beam lifetime at high energies, and increase the energy spread and bunch length at low energies. If the dispersion or slop of the dispersion is not zero at the collision point, beamstrahlung will also affect the transverse emittance.

The code Synrad3D, developped at Cornell University by D. Sagan in collaboration with G. Dugan is being employed to map the SR distribuation a long the LHC and future colliders.
