This white paper summarizes the activities of the Brazilian community concerning dark matter physics and highlights the importance of financial support to Brazilian groups that are…
Using b-tagging to enhance the SUSY reach of the CERN Large Hadron Collider
P. G. Mercadante, J. K. Mizukoshi, Xerxes Tata
Assuming that supersymmetry is realized with parameters in the hyperbolic branch/focus point (HB/FP) region of the minimal supergravity (mSUGRA) model, we show that by searching fo…
