A variety of recent measurements determining sides of the CKM unitarity triangle have been performed with Babar data and will be reported. These include: a measurement of |Vcb| and the form-factor slope in B -> D l nu Decays in events tagged by a fully reconstructed B meson; measurement and interpretation of moments in inclusive decays B->Xc l nu; measurement of |Vub| from form-factor shapes...

Low energy precision tests provide a probe on new physics which can complement the LHC. One such test is of first row CKM unitarity, which we are using to place limits on MSSM parameters. We scanned over the parameter space of the MSSM, and computed corrections to the Fermi constant for beta decay as a function of MSSM parameters. These corrections lead to apparent violations of first row...

We present a search for the fully leptonic B decay B+ -> tau+ nutau in 4.59x 10^8 B Bbar pairs collected at the Upsilon(4S) resonance using the BaBar detector. We select a sample of events with a reconstructed hadronic B decay, B- -> D^{0} X^{-}$, where $X$ represents a combination of charged and neutral light mesons; in the remainder of each event we search for the B+ -> tau+ nutau signal.

We report on recent results from BABAR on radiative penguin decays of B mesons including a
study of B → Xd γ decays and determination of |Vtd/Vts| and a measurement of B → Xs γ branching fraction and CP asymmetry.

We report on recent results from BABAR on searches for new physics including: search for invisible decays of the Upsilon(1S); search for baryon and lepton number violation in B decays; searches for lepton flavour violation and tests of universality in the decays of the tau and narrow Upsilon states; and a search for a Light Scalar in Radiative Transitions $\Upsilon\to\gamma A^0$.

We study gaugino mass generation in the context of semi-direct gauge
mediation models, where the messengers are charged under both the hidden
sector and the standard model gauge groups while they do not play
important roles in dynamical supersymmetry breaking. We clarify the
cancellation of the leading contributions of the supersymmetry breaking
effects to the gaugino mass in this class...

The ongoing LHC experiment shall be able to probe gluino and squark masses up to values of about 1 TeV. Assuming that hints for such a superpartner are found, we explore the constraints on the CMSSM parameter space provided by flavour and CPV observables. We also characterize the predictions of U(1) and SU(3) flavour models in such a scenario, and indicate which processes are best suited to...
