This study estimated the difficulty of various sit-ups tests using an item response theory (IRT) model, the Rasch Poisson Counts model. Scores were obtained on 18 sit-ups tests. All tests were… (More)

The decays $K_L \to \gamma\gamma$ and $K_L \to \ell^+ \ell^- \gamma$ are studied at the leading order $p^6$ in Chiral Perturbation Theory. One-loop contributions stemming from the odd intrinsic… (More)

The decays KL → γγ and KL → l+l− γ are studied at the leading order p6 in Chiral Perturbation Theory. One-loop contributions stemming from the odd intrinsic parity | ∆S |= 1 effective Lagrangian of… (More)

The double lepton pair decay modes of the K_L meson are analyzed including all contributions of order p^6 in Chiral Perturbation Theory. The experimentally established e^+ e^- e^+ e^- mode and the… (More)

The double lepton pair decay modes of the K{sub L} meson are analyzed including all contributions of order p{sup 6} in chiral perturbation theory. The experimentally established e{sup +}e{sup… (More)

Abstract The decays K L → γγ and K L → l + l − γ are studied at the leading order p 6 in chiral perturbation theory. One-loop contributions stemming from the odd intrinsic parity | ΔS | = 1 effective… (More)

The decays K{sub L}{r_arrow}{gamma}{gamma} and K{sub L}{r_arrow}l{sup +}l{sup {minus}}{gamma} are studied at the leading order p{sup 6} in Chiral Perturbation Theory. One-loop contributions stemming… (More)

The Goldberger-Treiman discrepancy in SU(3) is analyzed in the framework of heavy baryon chiral perturbation theory (HBChPT). It is shown that the discrepancy at leading order is entirely given by… (More)
