“…The first of these is B d → Kµµ, for which the bound [40] is λ 22 λ 23 < 2.3 × 10 −4 , compared to my estimate of 3 × 10 −5 . The other two processes are the radiative lepton decays µ → eγ and τ → µγ, which can be mediated by a loop containing a leptoquark and a quark of the third generation.…”

If electroweak symmetry breaking arises via strongly-coupled physics, the observed suppression of flavour-changing processes suggests that fermion masses should arise via mixing of elementary fermions with composite fermions of the strong sector. The strong sector then carries colour charge, and may contain composite leptoquark states, arising either as TeV scale resonances, or even as light, pseudo-Nambu-Goldstone bosons. The latter, since they are coupled to colour, get a mass of the order of several hundred GeV, beyond the reach of current searches at the Tevatron. The same generic mechanism that suppresses flavour-changing processes suppresses leptoquark-mediated rare processes, making it conceivable that the many stringent constraints may be evaded. The leptoquarks couple predominantly to third-generation quarks and leptons, and the prospects for discovery at LHC appear to be good. As an illustration, a model based on the Pati-Salam symmetry is described, and its embedding in models with a larger symmetry incorporating unification of gauge couplings, which provide additional motivation for leptoquark states at or below the TeV scale, is discussed.

“…Another aspect of the present architecture is concerned with performing polarization analysis. Similar to the multiphoton entanglement experiment [48][49][50][51][52], polarization analysis can be performed in each of the n outputs via quarter-and half-wave plates in front of polarizing beam splitters.…”

We investigate optimization of dichotomic local phase measurement settings for multipartite quantum systems. We first describe a method of constructing a single multipartite Bell inequality by treating the correlation function as an nindex tensor. Under a set of local phase measurement settings, we calculate the quantum prediction of the generalized Greenberger-Horne-Zeilinger state and show the exact relationship between quantum prediction and the phase factors. We show that there exists a set of optimal measurement settings relevant to maximal quantum prediction, which can contribute to testing multipartite Bell inequality in a straightforward manner. Also, we provide quantum simulation and numerical analysis with these optimal measurement settings.

“…is also a FCNC process, with an amplitude expressed in terms of hadronic form factors and the C 7 , C 9 , and C 10 Wilson Coefficients [6]. The angular distributions of B → K * + − , specifically the K * longitudinal polarization, F L , and the forward-backward asymmetry, A F B , are notably sensitive to physics beyond the SM [12]- [13] and have been previously measured by various experiments [14]- [18].…”

→ ¯s transitions are flavour-changing neutral current (FCNC) processes that play an important role in the search for physics beyond the Standard Model (SM). Contributions from virtual particles in the loop are predicted to deviate observables, such as the branching fraction, from their SM expectations. Using data from the BaBar experiment, we present the first search for the rare decay B + → K + τ + τ − . The BABAR results on the measurement of the angular asymmetries of B → K * + − , where = e or µ, are also reported. In addition, using a time-dependent analysis of B → K 0 S π + π − γ, the mixing induced CP-asymmetry for the radiative FCNC decay, B → K 0 S ργ, is measured, along with an amplitude analysis of the mKπ and mKππ spectrum.
