Many beyond the standard model theories include a stable dark matter candidate that yields missing or invisible energy in collider detectors. If observed at the CERN Large Hadron Collider, we must determine if its mass and other properties (and those of its partners) predict the correct dark matter relic density. We give a new procedure for determining its mass with small error.

Model Independent Search in 2-Dimensional Mass Space
A method to search for particles of unknown masses in events with missing energy is presented. The only assumption is the topology of the decay chain. The solvability of the event has significant
Probing CP violation with kinematic reconstruction at the LHC
We discuss the potential of observing effects of CP‐violation phases in squark decay chains at the LHC [1]. As the CP‐odd observable, we use the asymmetry composed by triple products of final state
Momentum reconstruction at the LHC for probing CP-violation in the stop sector
We study the potential to observe CP-violating effects in SUSY cascade decay chains at the LHC. Asymmetries composed by triple products of momenta of the final state particles are sensitive to
A review of the mass measurement techniques proposed for the Large Hadron Collider
We review the methods which have been proposed for measuring masses of new particles at the Large Hadron Collider paying particular attention to the kinematical techniques suitable for extracting

Neutralino reconstruction at the LHC from decay-frame kinematics
Decay-frame Kinematics (DK) has previously been introduced as a technique to reconstruct neutralino masses from their three-body decays to leptons. This work is an extension to the case of two-body
Mass determination in sequential particle decay chains
A simple method is proposed for determining the masses of new particles in collider events containing a pair of decay chains (not necessarily identical) of the form Z ? Y+1, Y ? X+2, X ? N+3, where
Effects of QCD radiation on inclusive variables for determining the scale of new physics at hadron colliders
We examine the effects of QCD initial-state radiation on a class of quantities, designed to probe the mass scale of new physics at hadron colliders, which involve longitudinal as well as transverse
Probing CP violation with and without momentum reconstruction at the LHC
We study the potential to observe CP-violating effects in SUSY cascade decay chains at the LHC. We consider squark and gluino production followed by subsequent decays into neutralinos with a


Determining SUSY model parameters and masses at the LHC using cross-sections, kinematic edges and other observables.
We address the problem of mass measurements of supersymmetric particles at the Large Hadron Collider, using the ATLAS detector as an example. By using Markov Chain sampling techniques to combine
New supersymmetry mass reconstruction method at the CERN LHC
We propose a new mass reconstruction technique for SUSY processes at the LHC. The idea is to completely solve the kinematics of the SUSY cascade decay by using the assumption that the selected events
Measuring sparticle masses in non-universal string inspired models at the LHC
We demonstrate that some of the suggested five supergravity points for study at the LHC could be approximately derived from perturbative string theories or M-theory, but that charge and colour
Warped unification, proton stability, and dark matter.
We show that solving the problem of baryon-number violation in nonsupersymmetric grand unified theories (GUT's) in warped higher-dimensional spacetime can lead to a stable Kaluza-Klein particle. This
Measurements of Masses in SUGRA Models at LHC
This paper presents new measurements in a case study of the minimal SUGRA model with m_0=100 GeV, mhalf=300 GeV, A_0=0, tan(beta)=2.1, and mu=+1 based on four-body distributions from three-step
Precision SUSY measurements at CERN LHC
If supersymmetry exists at the electroweak scale, then it should be discovered at the CERN Large Hadron Collider (LHC). Determining masses of supersymmetric particles, however, is more difficult. In

TeV symmetry and the little hierarchy problem
Constraints from precision electroweak measurements reveal no evidence for new physics up to 5–7 TeV, whereas naturalness requires new particles at around 1 TeV to address the stability of the
Supersymmetry and the LHC inverse problem
Given experimental evidence at the LHC for physics beyond the standard model, how can we determine the nature of the underlying theory? We initiate an approach to studying the ``inverse map from the
