Both components of the transverse electron polarization emitted in the beta decay of polarized, free neutron have been measured at cold neutron spallation source SINQ (PSI, Villigen). The T-odd, P-odd correlation coefficient associated with polarization component perpendicular to the neutron polarization and electron momentum, was found to be R= 0.008+/-0.015. This value is consistent...

We present updates on the searches for three $D^0 \to V \eta$ decays, where the $D^0$ comes from the decay $D^{*+}\to D^0 \pi^+$ and $V$ is a $\phi$, $\omega$ or $K^*$ vector meson. These results use a 467~fb$^{-1}$ data sample collected with the {\sl B{\scriptsize A}B{\scriptsize AR}} detector at SLAC.

We present preliminary results of the search for the doubly-radiative decay $D^{0} \rightarrow \gamma \gamma$ and the measurement of the branching fraction of its associated background $D^{0} \rightarrow \pi^{0}\pi^{0}$ in a data sample corresponding to an integrated luminosity of ~470fb$^{-1}$ collected with the BaBar detector at the PEP-II asymmetric $e^{+} e^{-}$ collider at SLAC. ...

We present a new method to test the Standard Model expectations at the LHC using photon-induced WW production. Both W decay in the main ATLAS or CMS detectors while scattered protons are measured in forward detectors. The sensitivity to anomalous WW gamma quartic and triple gauge coupling can be improved respectively by more than three orders of magnitude or a factor 30 compared to the...

We discuss the perspectives concerning a better determination of the proton structure in terms of quarks and gluons at LHC after describing the results coming from HERA and Tevatron. In a second part of the review, we describe the diffractive phenomena at HERA and Tevatron and the consequences for LHC. The focus will be given on perspectives for LHC, essentially on early measurements that...

The primordial power spectrum is important both for cosmological parameter estimation and for distinguishing between models of inflation. Many cosmological observables which probe inhomogenities are related to the power spectrum by a convolution with a transfer function. We show how two different deconvolution techniques, Tikhonov regularisation and the Backus-Gilbert method, can be used to...

I discuss string phenomenology, gauge threshold corrections and LARGE volume models. I describe scenarios for moduli stabilisation and supersymmetry breaking.
