DOI: 10.1007/jhep07(2021)230
Abstract: Abstract Leptonic and semileptonic meson decays that proceed via flavour-changing neutral currents provide excellent probes of physics of the standard model and beyond. We present explicit results for the Wilson coefficients of the weak effective… read more here.

DOI: 10.1007/jhep10(2021)235
Abstract: Abstract With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of $$ {\overline{B}}_{(s)}^0\to {D}_{(s)}^{\left(\ast \right)+}{L}^{-} $$ B… read more here.

DOI: 10.1088/1674-1137/42/3/033104
Abstract: Motivated by flavor non-universality and anomalies in semi-leptonic B-meson decays, we present a general and systematic discussion about how to construct anomaly-free $U(1)'$ gauge theories based on an extended standard model with only three right-handed… read more here.

DOI: 10.1103/physrevd.103.015026
Abstract: The CMS phase II track trigger may allow for a displaced dimuon vertex trigger with qualitatively lower ${p}_{T}$ thresholds than existing dimuon triggers. With this technique, we show that the CMS reach for exotic $B$-meson… read more here.

DOI: 10.1103/physrevd.105.035036
Abstract: Electron beam fixed target experiments such as NA64 and LDMX use missing energy-momentum to detect the production of dark matter and other long-lived states. The most studied production mechanism is dark Bremsstrahlung through a vector… read more here.

DOI: 10.1103/physrevd.95.073007
Abstract: The K-S(0)-K-L(0) asymmetries in the D-meson decays, induced by the interference between the Cabibbo-favored and the doubly Cabibbo-suppressed amplitudes, can help to understand the dynamics of charm decays. All possible processes of two-body nonleptonic D… read more here.

DOI: 10.1103/physrevlett.128.131802
Abstract: Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be… read more here.
