Prof. P. Fileviez Perez has been working on particle physics and cosmology. His research focuses on new ideas for physics beyond the Standard Model. The Standard Model of Particle Physics is one of the most successful theory of nature but it cannot explain many open issues in particle physics and cosmology. Fileviez Perez investigates new ideas which could lead to a more complete theory. Here is a list of some recent studies in particle physics and cosmology:
New Gauge Theories for Physics beyond the Standard Model: Prof. P. Fileviez Perez has proposed new theories where the baryon and lepton numbers can be defined as local symmetries spontaneously broken at the low scale. In this theories one can understand the proton stability and one has some interesting predictions for cosmology. These theories have the potential to change the standard paradigm for physics beyond the Standard Model, where one assumes a great desert between the electroweak scale and the scale where one has the possible unification of fundamental forces. In this context one does not need to postulate the great desert, the proton is stable and one can have the unification of the gauge forces at the low scale. For some relevant publications see:

Dark Matter in the Universe: The nature of the dark matter in the Universe is one of the interesting problems in modern cosmology. Prof. P. Fileviez Perez has investigated different theories for dark matter and the predictions for direct and indirect detection experiments. For some recent studies see:

Supersymmetric Theories: In the context of supersymmetric theories one can explain the possible unification of fundamental forces in nature. At the same time one could explain the properties of the dark matter and matter-antimatter asymmetry in the Universe. In this context Prof. P. Fileviez Perez has investigated new type of supersymmetric theories where one can understand dynamically the origin of the new interactions violating the baryon and lepton numbers. These interactions define the possible signatures at colliders and have profound implications in cosmology. See for example:
P. Fileviez Perez, S. Spinner, JHEP 1204 (2012) 118.
