Collective Quartics and Dangerous Singlets in Little Higgs

Martin Schmaltz, Jesse Thaler

Any extension of the standard model that aims to describe TeV-scale physics without fine-tuning must have a radiatively-stable Higgs potential. In little Higgs theories, radiative…

Phenomenology of SUSY with scalar sequestering

Gilad Perez, Tuhin S. Roy, Martin Schmaltz

The defining feature of scalar sequestering is that the MSSM squark and slepton masses as well as all entries of the scalar Higgs mass matrix vanish at some high scale. This ultrav…

Disentangling Neutrino Oscillations

Andrew G. Cohen, Sheldon L. Glashow, Zoltan Ligeti

The theory underlying neutrino oscillations has been described at length in the literature. The neutrino state produced by a weak decay is usually portrayed as a linear superpositi…

Low-scale gaugino mediation, lots of leptons at the LHC

Andrea De Simone, JiJi Fan, Martin Schmaltz +1

Low-scale gaugino mediation predicts that gauginos are significantly heavier than scalar superpartners. In order of increasing mass the lightest superpartners are the gravitino, ri…

Describing viable technicolor scenarios

Johannes Hirn, Adam Martin, Veronica Sanz

We construct an effective lagrangian for new strong interactions at the LHC, including as a first step the two lightest triplets of spin-1 resonances. Our parametrization is genera…

Accurate Mass Determinations in Decay Chains with Missing Energy

Hsin-Chia Cheng, Dalit Engelhardt, John F. Gunion +2

Many beyond the Standard Model theories include a stable dark matter candidate that yields missing / invisible energy in collider detectors. If observed at the Large Hadron Collide…

A composite gluino at the LHC

Thomas Gregoire, Emanuel Katz

We investigate the decay of particles with the quantum numbers of the gluino. Besides SUSY, such particles may be present in models where the Higgs and top are composite. We find t…

Flavour physics of leptons and dipole moments

M. Raidal, A. van der Schaaf, I. Bigi +82

This chapter of the report of the ``Flavour in the era of the LHC'' Workshop discusses the theoretical, phenomenological and experimental issues related to flavour phenomena in the…
