| Light vector-like quarks and the Higgs boson |
| Speaker: | Ivana Mustac (Josef Stefan Institute in Ljubljana) |
| Abstract: | Vector-like quarks are currently studied in increasing detail at the LHC, due to their importance in numerous models of New Physics. The current experimental null-results for their on-shell production have pushed the lower bounds on their masses near a TeV, however valid only under certain assumptions. Embedding vector-like quarks into models addressing the electroweak hierarchy problem by treating the Higgs as a pseudo-goldstone boson of a global symmetry changes current conclusions from flavour and electroweak precision tests and can have interesting implications for direct searches. We have studied the flavour phenomenology of such new states and calculated the implications for the electroweak hierarchy problem in light of recent Higgs data. |

| A tunable source of correlated atom beams |
| Speaker: | Marie BONNEAU (European Laboratory for NonLinear Spectroscopy, U Florence, Sesto Fiorentino, Italy) |
| Abstract: | I will present an experiment which enables production and characterization of macroscopic twin atomic beams. Spontaneous four wave mixing (SFWM) of matter waves is used as a source of non-classical atomic pair states, similar to the twin photon states generated through parametric down-conversion and widely used in quantum optics. In this experiment, SFWM is performed in a moving one-dimensional optical lattice, from a metastable helium BEC. The lattice modifies the dispersion relation of the atoms, so that pairs of atoms are efficiently scattered into two twin beams, whose momenta are precisely tunable. Like their photonic analog, the two atomic beams are correlated in momentum, and their population difference exhibits sub-shot noise fluctuations. These properties, and the ability to control the beams population, makes this source suitable for a variety of quantum atom optics experiments, in the limit of either high or low mode occupancy. |
