Minimal flavored U(1)′ for B -meson anomalies

Abstract

We consider an anomaly-free U (1) model with favorable couplings to heavy flavors in the Standard Model(SM), as motivated by B-meson anomalies at LHCb. Taking the, we can explain the B-meson anomalies without invoking extra charged fermions or flavor violation beyond the SM. We show that there is a viable parameter space with a small x that is compatible with other meson decays, tau lepton and neutrino experiments as well as the LHC dimuon searches. We briefly discuss the prospects of discovering the Z gauge boson at the LHC in the proposed model.

Holographic interferences in strong-field ionization beyond the dipole approximation: The influence of the peak and focal-volume-averaged laser intensities

“…For instance, we take two trajectories with p yi 1 = −p yi 2 and p zi 1,2 = 0, which contribute to the ridge (p y = 0, p z = −T z +p C ) and have δp C z 1 = δp C z 2 , yielding ∆ϕ = 0 according to Eq. (11). In this way the remarkable relation between the main lobe of the quantum interference pattern and the PMD ridge due to Coulomb focusing is confirmed.…”

“…This follows from Eqs. (11) and (14), and the condition δp C z 1 + δp C z 2 = 0, fulfilled for these trajectories. In the case of multiple recollisions (at small values of the final |p x |), the ridge position is closer to zero: p (0) z = −T z +p C , wherep C is positive and determined by multiple recollisions, see Eq.…”

“…The reference beam of the holography scheme [6] is the directly ionized electron wave packet, while the signal beam is the electron wave packet scattered off the ionic core during recollision. This concept of strong-field holography enables to extract time-resolved information on the underlying electron dynamics [7][8][9] and on the molecular structure [10][11][12][13][14].…”

Nuclear electric dipole moment in the cluster model with a triton: Li7 and B11

“…In extended Higgs models, the leading contribution arises from the two-loop level Barr-Zee type diagram [180][181][182][183][184][185][186][187][188][189][190][191][192][193][194]. For supersymmetric models, a large contribution is generated from the one-loop level diagram [11,[195][196][197][198][199][200][201][202][203][204][205], together with the two-loop level diagrams [11,[206][207][208][209][210][211][212][213].…”

Cooper minimum of high-order harmonic spectra from an MgO crystal in an ultrashort laser pulse

“…Atoms and molecules irradiated by an intense laser pulse can produce high-order harmonic generation (HHG) [1][2][3][4][5][6][7][8][9][10][11][12][13]. Under the influence of the strong laser field, an electron can be ionized from the bound state, and accelerated in the continuum state, finally it can recombine with the ion and gives rise to the emission of extreme ultraviolet (XUV) radiation [10,14].…”
