Lepton flavor violating Higgs boson decays in seesaw models: New discussions

Nuclear Physics B, 2017
The lepton flavor violating decay of the Standard Model-like Higgs boson (LFVHD), h→μτ, is discussed in seesaw models at the one-loop level. Based on particular analytic expressions of Passarino–Veltman functions, the two unitary and 't Hooft Feynman ...

The Effects of Reaction Variables on Solution Polymerization of Vinyl Acetate and Molecular Weight of Poly(vinyl alcohol) Using Taguchi Experimental Design [PDF]

علوم و تکنولوژی پلیمر, 2009
Poly(vinyl acetate) is synthesized via solution polymerization, and then it is converted to poly(vinyl alcohol) by alkaline alcoholysis. The aim of the work study was to investigate statistically the  influence of reaction variables in vinyl acetate ...

Final State Interaction Effects in B+→J/ψ π+ Decay [PDF]

Journal of Sciences, Islamic Republic of Iran, 2014
In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less

Contributions of vector leptoquark to Ξb→Ξcτν¯τ decay

Nuclear Physics B, 2019
Motivated by the RD(⁎) anomalies in semileptonic B meson decay which can be explained by adding a single vector leptoquark U3(3,3,23) to the Standard Model, we further analyse the New Physics effects of vector leptoquark to the heavy baryon Ξb→Ξcτ−ν¯τ ...

Branching ratio estimates of τ− → π−η(′)ντ decays

EPJ Web of Conferences, 2017
We study the rare τ− → π−η(′)ντ decays. These processes occur via isospin violation and belong to the so-called second-class currents unseen in Nature so far.

Semileptonic decay of $$\varOmega _c^0 \rightarrow \varXi ^- l^+ \nu _l$$ Ω c 0 → Ξ - l + ν l from light-cone sum rules

European Physical Journal C: Particles and Fields, 2021
The weak decay process of $$\varOmega _c$$ Ω c to $$\varXi $$ Ξ is calculated in the method of QCD light-cone sum rule. The decay width of $$\varOmega _c^0 \rightarrow \varXi ^- l^+ \nu _l$$ Ω c 0 → Ξ - l + ν l and its decay branching ratio are also ...

Measurement of D-meson branching ratios

Physics Letters B, 1986
Abstract Charm data from 360 GeV/c π− p interactions are used to give results on D-meson branching ratios. The analysis is based on 114 charm events containing 183 observed charm particle decays. We present topological branching ratios and decay multiplicities, as well as the following inclusive branching ratios of D-mesons: B( D ± → K
