One century after its formulation, Einstein's general relativity (GR) has made remarkable predictions and turned out to be compatible with all experimental tests. Most of these tests probe the theory in weak-field regime, there are theoretical reasons believe that GR should modified when gravitational fields strong spacetime curvature is large. The best astrophysical laboratories strong-field gravity black holes neutron stars, whether isolated or binary systems. We review motivations...
In a recent paper we studied the effect of new-physics operators with different Lorentz structures on semileptonic $$ {\Lambda}_b\to {\Lambda}_c\tau {\overline{\nu}}_{\tau } decay. This decay is interest in light R(D (*)) puzzle \overline{B}\to {D}^{\left(\ast \right)}\tau decays. this work add tensor to extend our previous results and consider both model-independent new physics (NP) specific classes models proposed address puzzle. We show that measurement...
We present a dark sector model that reproduces the KOTO, MiniBooNE and muon anomalous magnetic moment anomalies. The is comprised of light scalar singlet $S$ has large coupling to slightly heavier sterile neutrino mixes with active neutrinos. couples standard fermions via Yukawa couplings, photons higher-dimensional coupling. KOTO signal result flavor-changing penguin process $K_L \to \pi^0 S$ followed by decay produced in neutrino-nucleus scattering at decays an $S$, which...
At present, there are outstanding discrepancies between standard model predictions and measurements of the muon's $g\ensuremath{-}2$ several $B$-meson properties. We resolve these anomalies by considering a two-Higgs-doublet extended to include leptoquarks dark Higgs boson $S$. The modify decays also induce an $S\ensuremath{\gamma}\ensuremath{\gamma}$ coupling, which contributes through Barr-Zee diagram. show that, for TeV-scale masses ${m}_{S}\ensuremath{\sim}10--200\text{ }\text{...
