\( {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} \) and neutrino mass in the 2HDM-III with right-handed neutrinos

Abstract Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the \( {R}_{D^{\left(*\right)}} \) anomalies while the resolution to the \( {R}_{K^{\left(*\right)}} \) deficits requires new degrees of freedom within this framework, we consider in this paper a unified scenario where the low-scale type-I seesaw mechanism is embedded into the 2HDM...

The \(\varvec{\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-}\) decay in the aligned two-Higgs-doublet model

The rare baryonic decay \(\Lambda _b\rightarrow \Lambda (\rightarrow p\pi ^-)\mu ^+\mu ^-\) provides valuable complementary information compared to the corresponding mesonic \(b\rightarrow s\mu ^+\mu ^-\) transition. In this paper, using the latest high-precision lattice QCD calculation of the \(\Lambda _b\rightarrow \Lambda \) transition form factors, we study this interesting...

\(\varvec{B^0\rightarrow K^{*0}\mu ^+\mu ^-}\) decay in the aligned two-Higgs-doublet model

In the aligned two-Higgs-doublet model, we perform a complete one-loop computation of the short-distance Wilson coefficients \(C_{7,9,10}^{(\prime )}\), which are the most relevant ones for \(b\rightarrow s\ell ^+\ell ^-\) transitions. It is found that, when the model parameter \(\left| \varsigma _{u}\right| \) is much smaller than \(\left| \varsigma _{d}\right| \), the charged...

\( {\varLambda}_b\to {\varLambda}_c\tau {\overline{\nu}}_{\tau } \) decay in scalar and vector leptoquark scenarios

It has been shown that the anomalies observed in \( \overline{B}\to {D}^{\left(\ast \right)}\tau {\overline{\nu}}_{\tau } \) and \( \overline{B}\to \overline{K}{\ell}^{+}{\ell}^{-} \) decays can be resolved by adding a single scalar or vector leptoquark to the Standard Model, while constraints from other precision measurements in the flavour sector can be satisfied without fine...

Revisiting the one leptoquark solution to the R(D (∗)) anomalies and its phenomenological implications

It has been shown recently that the anomalies observed in \( \overline{B}\to {D}^{\left(*\right)}\tau {\overline{\nu}}_{\tau } \) and \( \overline{B}\to \overline{K}{\ell}^{+}{\ell}^{-} \) decays could be resolved with just one scalar leptoquark. Fitting to the current data on R(D(∗)) along with acceptable q 2 distributions in \( \overline{B}\to {D}^{\left(\ast \right)}\tau...

Revisiting \(B_s \rightarrow \mu ^+\mu ^-\) in the two-Higgs doublet models with \(Z_2\) symmetry

We revisit the rare leptonic decay \(B_s \rightarrow \mu ^+ \mu ^-\) in the two-Higgs doublet models (2HDMs) with a softly broken \(Z_2\) symmetry, namely type-I, type-II, type-X and type-Y 2HDMs. We have derived the relevant full one-loop Wilson coefficients of the four 2HDMs from the recent calculation in the aligned 2HDM by Li, Lu and Pich, which could be mapped to all the...

Phenomenological discriminations of the Yukawa interactions in two-Higgs doublet models with \(Z_2\) symmetry

There are four types of two-Higgs doublet models under a discrete \(Z_2\) symmetry imposed to avoid tree-level flavor-changing neutral current, i.e. type-I, type-II, type-X, and type-Y models. We investigate the possibility to discriminate the four models in the light of the flavor physics data, including \(B_s\)–\(\bar{B}_s\) mixing, \(B_{s,d} \rightarrow \mu ^+ \mu ^-\), \(B...

Whole genome nucleosome sequencing identifies novel types of forensic markers in degraded DNA samples

In the case of mass disasters, missing persons and forensic caseworks, highly degraded biological samples are often encountered. It can be a challenge to analyze and interpret the DNA profiles from these samples. Here we provide a new strategy to solve the problem by taking advantage of the intrinsic structural properties of DNA. We have assessed the in vivo positions of more...
