Kansas women in agriculture
No full textMaster of AgribusinessDepartment of Agricultural EconomicsMykel R. TaylorWomen have long worked on farms and ranches, although recognition of women involved in agriculture has only become more common in recent years. In the 2017 Census of Agriculture, changes were made to define a producer on a farm. This change allowed for greater recognition of women involved in farming. Kansas saw an increase in female producers involved in agriculture with the change. This study utilizes a survey sent out to women in agriculture who participated in a four-week financial series by K-State Research and Extension. The goal of the survey was to learn more about who these women were, what they wanted to learn, and how they wanted to learn. The results of the study can be used to design programming that will better meet their needs and make them more successful.
Survey results were analyzed and summarized to learn more about women in Kansas agriculture. Questions were asked relating to the demographics of the women followed by their employment, work they do on the farm or ranch, what decisions they are involved in on the farm or ranch, and what type of learning experience they are most interested in. Using USDA data for women in Kansas and comparing that information to the survey results gave an idea of the validity of the sample and similarities.
Women were able to select the programs that were of the most interest to them. There were 20 options to choose from and women could select as many as programs as they wanted. This information was then compared for the top four categories based on education, compensation, and main occupation. After comparing the top categories tables were created showing the most selected program types based on the main occupation of the respondents whether they were on the farm or ranch or involved in another occupation

Test of Lepton-Flavor Universality in B → K*l⁺l⁻ Decays at Belle
No full textWe present a measurement of R-K(*), the branching fraction ratio B(B -> K* mu(+)mu(-))/B(B -> K* e(+) e(-)), for both charged and neutral B mesons. The ratio for the charged case RK*+ is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q(2). The analysis is based on a data sample of 711 fb(-1), containing 772 x 10(6) B (B) over bar events, recorded at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. The obtained results are consistent with standard model expectations.LPH
Measurement of the branching fractions for Cabibbo-suppressed decays D+→K+K−π+π0 and D(s)+→K+π−π+π0 at Belle
No full textWe present measurements of the branching fractions for the singly Cabibbo-suppressed decays D+→K+K−π+π0 and D+s→K+π−π+π0, and the doubly Cabibbo-suppressed decay D+→K+π−π+π0, based on 980 fb−1 of data recorded by the Belle experiment at the KEKB e+e− collider. We measure these modes relative to the Cabibbo-favored modes D+→K−π+π+π0 and D+s→K+K−π+π0. Our results for the ratios of branching fractions are B(D+→K+K−π+π0)/B(D+→K−π+π+π0)=(11.32±0.13±0.26)%, B(D+→K+π−π+π0)/B(D+→K−π+π+π0)=(1.68±0.11±0.03)%, and B(D+s→K+π−π+π0)/B(D+s→K+K−π+π0)=(17.13±0.62±0.51)%, where the uncertainties are statistical and systematic, respectively. The second value corresponds to (5.83±0.42)×tan4θC, where θC is the Cabibbo angle; this value is larger than other measured ratios of branching fractions for a doubly Cabibbo-suppressed charm decay to a Cabibbo-favored decay. Multiplying these results by world average values for B(D+→K−π+π+π0) and B(D+s→K+K−π+π0) yields B(D+→K+K−π+π0)=(7.08±0.08±0.16±0.20)×10^−3, B(D+→K+π−π+π0)=(1.05±0.07±0.02±0.03)×10^−3, and B(D+s→K+π−π+π0)=(9.44±0.34±0.28±0.32)×10^−3, where the third uncertainty is due to the branching fraction of the normalization mode. The first two results are consistent with, but more precise than, the current world averages. The last result is the first measurement of this branching fraction
Search for violation in decays and observation of the Cabibbo-suppressed decay
No full textWe search for violation by measuring a -odd asymmetry in the
Cabibbo-suppressed decay, and
in the Cabibbo-favored and
decays. We use 980 of data collected by the Belle detector running at the KEKB
asymmetric-energy collider. The -violating -odd parameter
is measured to be

uncertainty is statistical and the second is systematic. We also report the
first observation of the Cabibbo-suppressed decay . The branching fraction is measured relative to
that of the analogous Cabibbo-favored decay :
Measurement of branching-fraction ratios and CP asymmetries in B± → DCP±K± decays at Belle and Belle II
No full textAbstract We report results from a study of B ± → DK ± decays followed by D decaying to the CP-even final state K + K − and CP-odd final state K S 0 π 0 , where D is an admixture of D 0 and D ¯ 0 states. These decays are sensitive to the Cabibbo-Kobayashi-Maskawa unitarity-triangle angle ϕ 3. The results are based on a combined analysis of the final data set of 772 × 106 B B ¯ pairs collected by the Belle experiment and a data set of 198 × 106 B B ¯ pairs collected by the Belle II experiment, both in electron-positron collisions at the Υ(4S) resonance. We measure the CP asymmetries to be A CP+ = (+12.5 ± 5.8 ± 1.4)% and A CP− = (−16.7 ± 5.7 ± 0.6)%, and the ratios of branching fractions to be R CP+ = 1.164 ± 0.081 ± 0.036 and R CP− = 1.151 ± 0.074 ± 0.019. The first contribution to the uncertainties is statistical, and the second is systematic. The asymmetries A CP+ and A CP− have similar magnitudes and opposite signs; their difference corresponds to 3.5 standard deviations. From these values we calculate 68.3% confidence intervals of (8.5 ° < ϕ 3 < 16.5 ° ) or (84.5 ° < ϕ 3 < 95.5 ° ) or (163.3 ° < ϕ 3 < 171.5 ° ) and 0.321 < r B < 0.465
Study of the K+ pi(+) pi(-) final state in B+ -> J/psi K+ pi(+) pi(-) and B+ -> psi ' K+ pi(+) pi(-)
No full textUsing 535 X 10(6) B-meson pairs collected by the Belle detector at the KEKB e(+)e(-) collider, we measure branching fractions of (7.16 +/- 0.10(stat) +/- 0.60(syst) X 10(-4) for B+ -> J/psi K+ pi(+) pi(-) and (4.31 +/- 0.20(stat) +/- 0.50(syst)) X 10(-4) for B+ -> psi' K+ pi(+) pi(-). We perform amplitude analyses to determine the resonant structure of the K+ pi(+) pi(-) final state in B+ -> J/psi K+ pi(+) pi(-) and B+ -> psi' K+ pi(+) pi(-) and find that the K-1(1270) is a prominent component of both decay modes. There is significant interference among the different intermediate states, which leads, in particular, to a striking distortion of the rho line shape due to the omega. Based on the results of the fit to the B+ -> J/psi K+ pi(+) pi(-) data, the relative decay fractions of the K-1(1270) to K rho, K omega, and K*(892)pi are consistent with previous measurements, but the decay fraction to K-0(*)(1430) is significantly smaller. Finally, by floating the mass and width of the K-1(1270) in an additional fit of the B+ -> J/psi K+ pi(+) pi(-) data, we measure a mass of (1248.1 +/- 3.3(stat) +/- 1.4(syst)) MeV/c(2) and a width of (119.5 +/- 5.2(stat) +/- 6.7(syst)) MeV/c(2) for the K-1(1270).LPH
Angular analysis of the low K+K− invariant mass enhancement in B+→K+K−π+ decays
No full textWe study the decay B+→K+K−π+ and investigate the angular distribution of K+K− pairs with invariant mass below 1.1 GeV/c2. This region exhibits both a strong enhancement in signal and very large direct CP violation. We construct a coherent sum model for the angular distribution of S- and P-wave, and report the ratio of their amplitudes, the relative phase and the forward-backward asymmetry. We also report absolute differential branching fractions and direct CP asymmetry for the decay in bins of MK+K− and the differential branching fractions in bins of MK+π−. The results are based on a data sample that contains 772×10^6 BB ̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e− collider. The measured overall branching fraction and the direct CP asymmetry are (5.38±0.40±0.35)×10^−6 and −0.170±0.073±0.017, respectively, where the first uncertainties are statistical and the second are systematic
Measurement of asymmetries in decays at Belle II
No full textWe report a measurement of decay-time dependent charge-parity () asymmetries in decays. We use pairs collected at the resonance with the Belle II detector at the SuperKEKB asymmetric-energy electron-positron collider. We reconstruct 220 signal events and extract the -violating parameters and from a fit to the distribution of the decay-time difference between the two mesons. The resulting confidence region is consistent with previous measurements in and decays, and with predictions based on the standard model
