A benefit‐cost analysis of child care subsidy expansions: The New York State case

Contemporary Economic Policy, EarlyView.
Abstract Proposals to expand child care assistance have proliferated at the national and state levels. This paper uses a novel approach to estimate the benefits and costs of providing child care subsidies to families up to three times the federal poverty line while supplementing child care worker compensation — a recently‐enacted reform in New York ...

Dispersion relations for hadronic light-by-light scattering and the muon g – 2

EPJ Web of Conferences, 2018
The largest uncertainties in the Standard Model calculation of the anomalous magnetic moment of the muon (g – 2)μ come from hadronic effects, and in a few years the subleading hadronic light-by-light (HLbL) contribution might dominate the theory error ...

Pion generalized parton distributions and light-front wave functions in the Nambu–Jona-Lasinio model

Nuclear Physics B, 2021
Pion generalized parton distributions and light-front wave functions are investigated in the framework of Nambu–Jona-Lasinio model. The properties of pion generalized parton distributions and light-front wave functions are examined separately. Proceeding

Phase Transition in Hot Pion Matter [PDF]

, 2000
The equation of state for the pion gas is analyzed within the third virial approximation. The second virial coefficient is found from the pion-pion- scattering data, while the third one is considered as a free parameter.

Improved parton distribution functions at the physical pion mass [PDF]

Physical Review D, 2017
We present the first lattice results on isovector unpolarized and longitudinally polarized parton distribution functions (PDFs) at physical pion mass. The PDFs are obtained using the large-momentum effective field theory (LaMET) framework where the full ...

Bioactivity and physicochemical characterization of Centella asiatica and Marigold extract serums: Antioxidant, anti‐inflammatory, anti‐tyrosinase and skin barrier function insights

International Journal of Cosmetic Science, EarlyView.
Evaluation of Centella asiatica extract and Marigold extract serums, optimizing their concentrations for antioxidant, anti‐inflammatory, antibacterial, and skin barrier‐enhancing effects. It uniquely combines bioactivity, stability, and permeability assessments, revealing Centella asiatica extract's superior regenerative potential and Marigold extract ...

Pion nucleus Drell–Yan process and parton transverse momentum in the pion

European Physical Journal C: Particles and Fields, 2018
We present a thorough analysis of unpolarized Drell–Yan (DY) pair production in pion–nucleus scattering. On the nucleus side, we use nuclear parton distributions along with parametrisations of the nucleon partonic transverse distribution available in the

Equivalence of Nonstatic Two-Pion-Exchange Nucleon-Nucleon Potentials

, 1999
Off-shell aspects of the one-pion-exchange potential and their relationship to different forms of the nonstatic (subleading-order) chiral two-pion-exchange nucleon-nucleon potential are discussed.

Pion Propagation near the QCD Chiral Phase Transition [PDF]

, 2001
We point out that, in analogy with spin waves in antiferromagnets, all parameters describing the real-time propagation of soft pions at temperatures below the QCD chiral phase transition can be expressed in terms of static correlators.

Pion-less effective field theory for atomic nuclei and lattice nuclei [PDF]

Physical Review C, 2017
We compute the medium-mass nuclei 16O and 40Ca using pion-less effective field theory (EFT) at next-to-leading order (NLO). The low-energy coefficients of the EFT Hamiltonian are adjusted to experimental data for nuclei with mass numbers A=2 and 3, or ...
