No full textGenre: Language (expression). Title: Du'ane pi'i (Perfect aging). Lakimosa Sundu, kampong Ko'a, tells how he remembers his grandfather. He uses two typical expressions to describe the state of old age, "Perfect aging. Walking until crawling with a coconut shell. Standing straight with a staff". Recorded by SD with the AT2020 mic in the evening 13 June -15 in Sundu's home, sitting just the two of us.Palu'e, Flores, Nusa Tenggara Timur, Indonesia. Recording made in kampong/domain Ko'a
SD1-342
No full textGenre: adat. Title: Kena morene. Pitu Sopune recorded bapak lakimosa (priest-leader) Sundu, in his home in Ko'a, 12 Nov 2023. Sundu talks about local beliefs concerning animals, how the ancestors use them to communicate messages to the people. Sundu talks about boimesi cricket, heko kingfisher, sololika brown-tailed fanbird, nggole kéli pyton. The cricket comes to cry in the house by the hulu pitu house altar because is it hungry and thirsty, but actually it is the ancestors who require ceremonial rice, and perhaps they feel neglected. So, you put rice by the hulu pitu and utter bhulu wa'o prayer, mutually supporting, then it goes away. The kingfisher brigs notice of disease when it comes to the village, also of relatives' disease in far lands. Outside the village the sound is a notice of that evil people is approaching or about to decieve you, and there is a bhulu wa'o prayer for that too. The seasnake bha'i brings similar messages at sea. When seen at the surface in front of the boat, the ancestors inform that the situation is bad in the village, that people are ill and in hardship. When pytons are often seen near the village or even inside, it is a sign that the volcano is heating up and might erupt (traditional, indigenous ecological knowledge, reading the nature). The recording and the annotation work was supported by a Firebird Foundation Supplemental Research Grant for the Documentation of Oral Literature and Traditional Ecological Knowledge.

H+-> W+iota(-)(i)iota(+)(j) decay in the two Higgs doublet model
No full textWe study the lepton flavor violating (LFV) H+-->W(+)l(i)(-)l(j)(+) and the lepton flavor conserving (LFC) H+-->W(+)l(i)(-)l(i)(+) (l(i)=tau,l(j)=mu) decays in the framework of the general two Higgs doublet model, the so-called model III. We estimate the decay width of LFV (LFC) decay at the order of magnitude of 10(-11)-10(-5) GeV (10(-9)-10(-4) GeV), for 200 GeVless than or equal tom(H+/-)less than or equal to400 GeV, and intermediate values of the coupling (xi) over bar (E)(N,taumu)similar to5 GeV ((xi) over bar (E)(N,tautau)similar to30 GeV). We observe that experimental results for the process under consideration can give comprehensive information about physics beyond the standard model and the existing free parameters
The strong decays of the light scalar mesons f0(500) and f0(980)
No full textAzizi, Kazem (Dogus Author)The partial width of the decay channels f0(500)→ππ f0(980)→ππ and f0(980)→KK¯ are calculated using QCD light-cone sum rules method and a technique of the soft meson approximation. The scalar particles are treated as mixtures of the heavy |H〉=([su][s¯u¯]+[sd][s¯d¯])/2 and light |L〉=[ud][u¯d¯] scalar diquark–antidiquark components. Obtained results for the full width of the f0(500) meson Γth.=434.7±72.3MeV and for the f0(980) meson Γth.=42.12±6.70MeV are compared with the world averages for these parameters, and a reasonable agreement between them is found
Spectroscopic parameters and decays of the resonance Z(b)(10610)
No full textAzizi, Kazem (Dogus Author)The resonance Zb(10610) is investigated as the diquark-antidiquark Zb = [bu][(b) over bar(d) over bar] state with spin-parity J(P) = 1(+). The mass and current coupling of the resonance Z(b)(10610) are evaluated using QCD two-point sum rule and taking into account the vacuum condensates up to ten dimensions. We study the vertices Z(b)r(nS)pi (n = 1, 2, 3) by applying the QCD light-cone sum rule to compute the corresponding strong couplings gZb.(nS) p and widths of the decays Z(b)-> r(nS)pi. We explore also the vertices Z(b)h(b)(mP)pi (m = 1, 2) and calculate the couplings gZ(b)h(b)(mP) p and the widths of the decay channels Z(b) -> hb(mP)pi To this end, we calculate the mass and decay constants of the h(b)(1P) and h(b)(2P) mesons. The results obtained are compared with experimental data of the Belle Collaboration
Treating Z(c)(3900) and Z(4430) as the ground state and first radially excited tetraquarks
No full textAzizi, Kazem (Doğuş Author)Exploration of the resonances Z(c)(3900) and Z(4430) are performed by assuming that they are the ground state and first radial excitation of the same tetraquark with J(P) = 1(+). The mass and current coupling of the Zc(3900) and Z(4430) states are calculated using the QCD two-point sum rule method by taking into account vacuum condensates up to eight dimensions. We investigate the vertices Z(c)M(h)M(l) and ZM(h)M(l), with M-h and M-l being the heavy and light mesons and evaluate the strong couplings g(ZcMhMl) and g(ZMhMl) using the QCD sum rule on the light cone. The extracted couplings allow us to find the partial width of the decays Z(c)(3900)-> J/psi pi, psi'pi, eta(c)rho and Z(4430)-> psi'pi, J/psi pi, eta'(c)rho, eta(c)rho which may help in comprehensive investigation of these resonances. We compare the width of the decays of Z(c)(3900) and Z(4430) resonances with available experimental data as well as existing theoretical predictions
tau -> mu(nu)over-bar(i)nu(i) decay in the general two Higgs doublet model
No full textWe study tau --> munu(i)nu(i), i = e, mu, tau decay in the model III version of the two Higgs doublet model. We calculated the BR at the order of magnitude 10(-6)-10(-4) for intermediate values of the Yukawa couplings. Furthermore, we predict the upper limit of the coupling for the tau-h(0)(A(0))-tau transition as similar to0.3 in the case that the BR is similar to10(-6). We observe that the experimental result of the process under consideration can give comprehensive information about the physics beyond the standard model and the free parameters existing
Tensor hybrid mesons b‾gc
No full textSpectroscopic parameters and widths of the tensor hybrid mesons Hbc and H˜bc with the structure b‾gc and spin-parities JP=2− and JP=2+ are calculated with high accuracy in the QCD sum rule framework. Information on their masses m=(7.214±0.075)GeV and m˜=(7.685±0.040)GeV enable us to determine decay channels of Hbc and H˜bc. The full width of the meson Hbc is estimated by considering the decays Hbc→D+B‾⁎0 and D0B⁎+. The channels H˜bc→B+D0, B0D+, B⁎+D⁎0, B⁎0D⁎+, Bs0Ds+, and Bs⁎0Ds⁎+ are studied to find the width of the H˜bc state. The widths of these processes are calculated using QCD three-point sum rule approach, which require estimation of the strong couplings at hybrid-meson-meson vertices. The results (50.8±9.8)MeV and (184.3±22.8)MeV for the full widths of the hybrid mesons Hbc and H˜bc characterize them as relatively narrow and broad structures, respectively
The structure, mixing angle, mass and couplings of the light scalar f(0)(500) and f(0)(980) mesons
No full textAzizi, Kazem (Dogus Author)The mixing angle, mass and couplings of the light scalar mesons f(0)(500) and f(0)(980) are calculated in the framework of QCD two-point sum rule approach by assuming that they are tetraquarks with diquark-antidiquark structures. The mesons are treated as mixtures of the heavy vertical bar H > = ([su][(s) over bar(u) over bar] + [sd][(s) over bar(d) over bar])/root 2 and light vertical bar L > = [ud][(u) over bar(d) over bar] scalar diquark-antidiquark components. We extract from corresponding sum rules the mixing angles phi(H) and phi(L) of these states and evaluate the masses and couplings of the particles f(0)(500) and f(0)(980)
Semileptonic bs -> ds2*(2573) l(nu)over-barl transition in QCD
No full textAzizi, Kazem (Dogus Author)We analyze the semileptonic B-s -> D-s2*(2573) l (nu) over bar (l) transition, where l = tau, mu or e, within the standard model. We apply the QCD sum rule approach to calculate the transition form factors entering the low energy Hamiltonian defining this channel. The fit functions of the form factors are used to estimate the total decay widths and branching fractions in all lepton channels. The orders of the branching ratios indicate that this transition is accessible at LHCb in the near future
