Research Group

The Experimental High Energy Physics group of BUAP has reached a solid degree of maturity in its theoretical and its experimentalthe area, as well as in the use of high-performance computing tools.

It maintains collaboration and presence at international level and its contributions have outstanding indices of readership. Its development is the product of work carried out for over twenty years on topicsissues from High Energy Cosmic Rays and the Higgs boson physics and the Quark Top to Standard Model Eextensions that include candidates for dark matter. Their participation in experiments such as In the experimental area, the participation in the Compact Muon Solenoid of the Large Hadron Collider, the  and in High Energy Astrophysics, such as the Pierre Auger Observatory and the High Altitude Water Cerenkov Observatory is well recognized and appreciated by the international community outstanding.

Research Interest

The research interest centers on the study of the structure and interactions of the fundamental constituents of matter, their phenomenology and the extensions of the standard model of particles. Phenomenology of elementary particles. Study of phenomenology of standard model of elementary particles and their extensions, as well as the experimental verification of predictions of these models.

Search for New Physics in Accelerators (LHC). Many of the theoretical proposals on New Physics are based on extensions dingof  the Higgs sector of the Standard Model. For example,T the group hasre is extensive experience in the Higgs multi-boson models, including their supersymmetric version, which predict a richer spectrum of new particles and phenomena that should be sought in the following stages of the LHC. Our research group actively participate in the projects related to this search at CERN.

New Theoretical Physics - Models and Foundations. Within the theoretical proposals, we have extensive experience in Higgs multi-boson models (including the Two Higgs Doublet Model), including its supersymmetric version, which predict a richer spectrum of new particles and phenomena than should be sought in the following stages of the LHC: It is of great interest to our group to study the predictions of such models for the Higgs sector, including the rare decays of quarks, leptons and Higgs bosons, as well as candidates for subject and dark energy

The Detection of Ultra-energetic Cosmic Phenomena (HAWC and Pierre Auger). In study of cosmic phenomena, an area also known as Astroparticle Physicss, is one of the research interests of the group. Oone of the great open problems in this field, is to investigatethe nature of dark matter and dark energy, as well as the ultra-energetic cosmic rays origins and compositionphenomena. These aspectscases are can be studied by the group members in the experimentsin HAWC and Pierre Auger experiments.


Current Member

Humberto A. Salazar Ibargüen Ph. D.

Dr. Salazar Ibargüen is head of the Director General General Directorate of the Computing and Information Technologies and Communications and Researcher of the Faculty of Physical Mathematics Sciences at BUAP. His contributions gave evidence of the existence of the Higgs Bosson.

 and made him a creditor of "The 2013 High Energy and Particle Physics Prize", granted by the European Physics Society.

He participates in the CMS (Compact Muon Solenoide) one of the biggest experiments at CERN (Erupean Organization for Nuclear Research), in Geneva, Switzerland, of the High Altitude Water Cherenkov Gamma Ray Observatory (HAWC) and the Pierre Auger Observatory, whose common purpose is to seek a new fundamental laws in Physics.

Salazar Ibargüen also participated in the design, construction and testing of the TUS UV camera (Tracking Ultraviolet Set up, or ultraviolet tracking device), the main scientific instrument installed on the M. Lomonosov Satellite, which was launched on April 28, 2016.

For his outstanding career, he obtained the Medal of Science and Technology "Luis Rivera Terrazas" 2016, in the Basic Science category in the area of Exact and Natural Sciences.

Isabel Pedraza Morales Ph.D.

Dr. Isabel Prof. Pedraza is now the first Mexican women, working in a Mexican institution, to hold a management appointment in one of the biggest scientific collaboration in the world, the CMS (Compact Muon Solenoide) collaboration of the LHC (Large Hadron Collider) at CERN (Erupean Organization for Nuclear Research). SheThere she  coordinates the Research and &Development (R&D) activities for the new muon detection technologies where 21 institutions from 11 countries are involved. Isabel PedrazaShe leads the efforts towards enhancing supercomputing and big data capabilities in Mexico as a member of the Academic and Technical Committee (CTA) of the Mexican National Supercomputing Network (RedMexSu). She is also part of the CTA of one of the biggest supercomputing laboratories in Mexico the National Supercomputing Laboratory of the Southwest (LNS). She has beenwas selected to be one of the 30 scientists under 40 that are doing promising work in the area of particle physics and neuroscience by the Chilean magazine Qué Pasa and in 2014. She is currently a Professor of the Faculty of Physics and Mathematics of the Meritorious Autonomous University of Puebla (MUAP), Mexico, and leads the research carried by the group from BUAPMUAP within the CMS Collaboration. Her main interests ins searching physics Beyond the Standard Model are thein extended Higgs sectors and the Dark Matter, where artificial intelligence methods are currently being used.

Carlos Enrique Varela Ph.D.

Researcher in Ultra High Energy Cosmic Rays, data science, the design of experiments for the study of cosmic rays,  with a particular focus on the mass composition and spectrum of cosmic rays elongation rate analysis, features of the spectrum of cosmic rays 2nd knee, ankle, using simulations Monte Carlo on supercomputing. Member of Pierre Auger Collaboration (International) for the study of ultra high energy cosmic rays since 2011. Co-founder of the National Supercomputing Laboratory of southeastern Mexico (LNS for its acronym in Spanish). Founder of the Center of Data Acquisition and Monitoring of the fluorescence detector (FD) of the Pierre Auger Observatory since Puebla in the BUAP.

Óscar Mario Martínez Bravo Ph.D

Ph.D. in Extragalactic Astronomy at INAOE in 1998, then he was related with few international astroparticle experiments as Pierre Auger Observatory, HAWC, and LAGO. Since 2005 he has been involved with the University Space Project in collaboration with the Moscow State University, composed by the Tatyana I and II missions and recently the TUS instrument on board of the M. Lomonosov Satellite launched in 2016. He has dictated courses at graduate and undergraduate levels, especially in the areas related to the experimentation. Complement these activities with talks of dissemination and public outreach in astronomy and science in general within several programs.
