לוח שנה משולב

On Wednesday, November 16th, we will be hosting a basic user seminar given by Dr. Gerhard Heinzmann a support specialist that is installing the new technology in the Protein Analysis Unit at LSCF.

The training session will take place in the Ullmann Building, Aharon Katzir Hall, from 9:00 AM – 11:00 AM [16/11]. It includes and introduction to FFF technology and basic tools for starting to work.

If you have any further questions regarding this training session, please contact Dana:

We show that the relaxion generically stops its rolling at a point that breaks CP leading to relaxion-Higgs mixing. This opens the door to a variety of observational probes since the possible relaxion mass span a broad range from sub-eV to GeV scale. We derive constraints from current experiments (fifth force, astrophysical and cosmological probes, beam dump, flavour, LEP and LHC) and present projections from future experiments such as NA62, SHiP and PIXIE. We find that a large region of the parameter space is already under the experimental scrutiny. All the experimental constraints we derive are equally applicable for general Higgs portal models. On the theoretical side we present a new bound on the back-reaction scale, Lambda^4_{br} < m_h^2 v^2. In addition, we show that simple multiaxion (clockwork) UV completions, suffer from a mild fine tuning problem, which increases with the number of sites. These results favour a cut-off scale lower than the existing theoretical bounds.
