“…As already mentioned, for this, and similar situations, a perturbative expansion in powers of η(x ) has been developed, in order to compute the Casimir energy, under the assumption that |η(x )| << a. This program has been carried out up to the second order in η [2], and applied, for example, to the evaluation of the effect of corrugations on the Casimir energy [2][3][4]. The perturbative calculations of Refs.…”

Fourth order perturbative expansion for the Casimir energy with a slightly deformed plate

2012

We apply a perturbative approach to evaluate the Casimir energy for a massless real scalar field in 3 + 1 dimensions, subject to Dirichlet boundary conditions on two surfaces. One of the surfaces is assumed to be flat, while the other corresponds to a small deformation, described by a single function η, of a flat mirror. The perturbative expansion is carried out up to the fourth order in the deformation η, and the results are applied to the calculation of the Casimir energy for corrugated mirrors in front of a plane. We also reconsider the proximity force approximation within the context of this expansion.

We consider the effective interaction of quarks with a new GeV-scale vector particle that couples to electroweak gauge bosons by the so-called effective Chern-Simons interaction. We call this particle the Chern-Simons (CS) boson. We construct effective Lagrangian of the CS boson interaction with quarks of two different flavors. This interaction is given by a divergent loop diagram, however, it turns out that the divergent part is equal to zero as a consequence of the CKM matrix unitarity in the SM. Therefore, we are able to predict effective interaction of the CS boson with quarks of different flavors without introducing new unknown parameters to the model, using only parameters of the initial effective Lagrangian. Our result shows that the effective interaction of the CS boson with down-type quarks is sufficiently stronger compared with up-type quarks. Based on our results, we give a prediction for the production of CS bosons in mesons decays. Branching fractions were obtained for the main reactions of the CS production in meson decays. The results obtained will be useful for searching for the long-lived GeV-scale CS boson in intensity frontier experiments.

A number of measurements in decays induced by the semileptonic $b\to s$ and $b\to c$ transitions hint towards a possible role of new physics in both sectors. Motivated by these anomalies, we investigate the lepton flavor violating $B\to K^*_2 (1430)\mu^{\pm}\tau^{\mp}$ decays. We calculate the two-fold angular distribution of $B\to K^*_2\ell_1\ell_2$ decay in presence of vector, axial-vector, scalar and pseudo-scalar new physics interactions. We then compute the branching fraction and lepton forward-backward asymmetry in the framework of $U^{2/3}_1$ vector leptoquark which is a viable solution to the current $B$ anomalies. We find that the upper limits are $\mathcal{B}(B\to K^*_2\mu^-\tau^+)\leq 1.64\times 10^{-7}$ and $\mathcal{B}(B\to K^*_2\mu^+\tau^-)\leq 0.60\times 10^{-7}$ at $90\%$ C.L.
