Mass Determination of New Particle States
Mario Serna
We study theoretical and experimental facets of mass determination of new particle states. Assuming supersymmetry, we update the quark and lepton mass matrices at the grand unifica…
Quasi-degenerate neutrinos and tri-bi-maximal mixing
Ivo de Medeiros Varzielas, Graham G. Ross, Mario Serna
We consider how, for quasi-degenerate neutrinos with tri-bi-maximal mixing at a high-energy scale, the mixing angles are affected by radiative running from high to low-energy scale…
Precision Determination of Invisible-Particle Masses at the CERN LHC: II
Alan J. Barr, Alex Pinder, Mario Serna
We further develop the constrained mass variable techniques to determine the mass scale of invisible particles pair-produced at hadron colliders. We introduce the constrained mass…
The Precision Determination of Invisible-Particle Masses at the LHC
Alan J. Barr, Graham G. Ross, Mario Serna
We develop techniques to determine the mass scale of invisible particles pair-produced at hadron colliders. We employ the constrained mass variable m_2C, which provides an event-by…
A short comparison between m_T2 and m_CT
Mario Serna
We compare m_T2 with m_CT; both are kinematic variables designed to find relationships between masses of pair-produced new states with symmetric decay chains. We find that for mass…
Mass Determination of New States at Hadron Colliders
Graham G. Ross, Mario Serna
We propose an improved method for hadron-collider mass determination of new states that decay to a massive, long-lived state like the LSP in the MSSM. We focus on pair produced new…
