The effect of external as well as internal bremsstrahlung radiation in H ! ZZ ! 4e channel is studied in full detector simulation. A method is proposed for external and internal bremsstrahlung recovery, allowing us to use 95% of electrons within j E=pgen 1 j 0.2. It is shown that traditional E=p and isolation cuts can be implemented with 90% efficiency, but that precise mass reconstruction is a...

In this paper, we present PICPA, the “Population and Interval Constraint Propagation Algorithm” which is able to produce high quality approximate solutions while giving guaranteed bounds for the Pareto optimal front. These bounds allow us to know whether the heuristic solutions are close to or far away from the optimal front. PICPA combines “Interval Constraint Propagation” (ICP) techniques [1,...

In this paper, we present a new computation scheme for pessimistic bilevel optimization problem, which so far does not have any computational methods generally applicable yet. We first develop a tight relaxation and then design a simple scheme to ensure a feasible and optimal solution. Then, we discuss using this scheme to compute linear pessimistic bilevel problem and several variants. We also...
