Abstract We conduct a model-independent analysis of the distinct signatures of various generic new physics possibilities in the decay $$B \rightarrow K \, \nu \, \overline{\nu }$$ B → K ν ν ¯ by analyzing the branching ratio as well as the missi

Abstract We propose a method of measuring the CP-odd part of the Yukawa interaction of Higgs boson and $$\tau $$ τ leptons by observing the forward–backward asymmetry in the decay $$H \rightarrow \tau ^+ \, \tau ^- \, \gamma $$ H → τ + τ - γ

Abstract Using the well established principles of Lorentz invariance, CP and CPT symmetry, and quantum statistics we do a model-independent study of effects of possible non-standard couplings of (Dirac and Majorana) neutrinos. The study is sensitive

Abstract The disagreement between the standard model prediction and the experimental measurement of muon anomalous magnetic moment can be alleviated by invoking an additional particle which is either a vector boson (X 1) or a scalar (X 0). This new p

Abstract We present, how a systematic study of $$B \rightarrow D\ell N$$ B→DℓN ($$D \rightarrow K \ell N$$ D→KℓN ) decays with $$\ell =\mu ,\tau $$ ℓ=μ,τ , at Belle II (BESIII) can provide unambiguous signature of a heavy neutrino N and/o

Abstract Of all B→DD¯ $$ B\to D\overline{D} $$ decays, the B0→D0D0¯ $$ {B}^0\to {D}^0\overline{D^0} $$ decay has the smallest observed branching ratio as it takes place primarily via the suppressed W-exchange diagram. The CP asymmetry for this

Abstract We present a fully general, model-independent study of a few rare semileptonic B decays that get dominant contributions from W-annihilation and W-exchange diagrams, in particular $$B^0 \rightarrow \overline{D}{} ^0 \ell ^+\ell ^-$$ B 0 → D

The nature of a neutrino, whether it is a Dirac type or Majorana type, may be comprehensively probed using their quantum statistical properties. If the neutrino is a Majorana fermion, then by definition it is identical and indistinguishable from the

We present, how a systematic study of $B \to D\ell N$ ($D \to K \ell N$) decays with $\ell=\mu,\tau$, at Belle II (BESIII) can provide unambiguous signature of a heavy neutrino $N$ and/or constrain its mixing with active neutrinos $\nu_\ell$, which i

The present anomaly in muon anomalous magnetic moment can be explained by the presence of a muon-philic $X$ boson which could be a scalar particle or a vector particle with mass less than twice the mass of muon. The muon-philic $X$ boson could intere
