Probing physics beyond the Standard Model
with micro black holes and neutrinos
Proiect: PN-II-RU-TE-2011-3-0184, no. 9/05/10/2011
funded by the Executive Agency for Higher Education, Research, Development and Innovation (UEFISCDI)
Abstract
The overall objective of the project is to look for signatures of quantum gravity and physics beyond the Standard Model of particle physics via lack holes production at the Large Hadron Collider, in ultra high energy cosmic rays data, and via the available data in the neutrino sector.
Clarifying the existence or nonexistence of black holes in the TeV range has consequences on many physics models. If the existence of TeV black holes is confirmed, this will be a clear statement about the scale of gravity being low, which can only happen in brane world models/extra dimensional theories.
This would also be a confirmation of string theory, which would be a very big step for the scientific community. It is also possible that the discrepancies which exist in the neutrino oscillations data are generated by physics beyond the Standard Model effects.
The general objectives of the research proposal are the following:
A) In order to constrain the parameter space for the tidal charged BHs, I propose an analysis of the time evolution for the mass of BHs which can be produced when UHECRs strike the surface of extremely dense astrophysical objects such as neutron stars;
B) On a related but separate topic, I intend to include the case of tidal charged BHs into the BlackMax event generator;
C) A search for possible signatures of TeV BHs in the data accumulated by the Pierre Auger Observatory;
D) Deeper analysis of the LSND and MiniBooNE anomalies. Further search for possible modifications of the neutrino dispersion relations, the possibility of neutrino-antineutrino oscillations, and for the implications of these possibilities. Detailed phenomenological analysis of the neutrino data for the case of neutrino-antineutrino oscillations.
The research ideas which will be developed throughout the duration of the present research proposal will not be limited to the ones specified above. In scientific research new ideas are continuously developed from old ones or as a result of research collaborations. Each of the objectives stated above is explained in detail in the full version of the research proposal, also available on this webpage.
