Exotic Searches at ATLAS

We present the first results of searches for new physics with the ATLAS detector using the 2010 Large Hadron Collider proton-proton collision data at a centre of mass energy of 7 TeV. After a few months of operation, these searches already go beyond the reach of previous experiments, and start to explore new territories.Comment: Conference proceedings for Moriond EW 201

Monte Carlo event generator for black hole production and decay in proton-proton collisions

We describe the Monte Carlo event generator for quantum black hole production and decay in proton-proton collisions -- QBH version 1.03.Comment: updated to version 1.03, now uses pythia 8.150, may not be backward compatable with older versions of pythia

Quasinormal modes of loop quantum black holes near the Planck scale

We compare four loop quantum gravity inspired black hole metrics near the Planck scale. Spin 0, 1/2, 1, and 2 field perturbations on these backgrounds are studied. The axial gravitational quasinormal modes are calculated and compared. The time evolution of the ringdown is examined. We also calculate the quasinormal modes in the eikonal limit and compare with the predictions from circular null geodesics.Comment: 21 pages, 8 figure
