Published in 2022 at "Journal of High Energy Physics"

DOI: 10.1007/jhep03(2022)101

Abstract: Abstract The new experiment data of muon g − 2 is reported by the workers at Fermilab National Accelerator Laboratory (FNAL). Combined with the previous Brookhaven National Laboratory (BNL) E821 result, the departure from the… read more here.

Published in 2017 at "Communications in Mathematical Physics"

DOI: 10.1007/s00220-016-2659-y

Abstract: In this paper, we study a new application of the positive Grassmannian to Wilson loop diagrams (or MHV diagrams) for scattering amplitudes in N= 4 Super Yang–Mill theory (N = 4 SYM). There has been much… read more here.

Published in 2025 at "Obesity Reviews"

DOI: 10.1111/obr.13966

Abstract: This scoping review characterizes the literature on qualitative systems methodologies that guide interest‐holders in developing causal loop diagrams focused on food systems, diet, and obesity. Peer‐reviewed research using interest‐holder–driven causal loop diagrams to examine food… read more here.

Published in 2025 at "BMJ Global Health"

DOI: 10.1136/bmjgh-2024-016342

Abstract: Introduction Despite progress in reducing Uganda’s unmet need for family planning (FP), particularly in urban areas, it remains high with notable intraurban disparities. FP services in urban settings are delivered in a complex health system,… read more here.

Published in 2025 at "BMC Public Health"

DOI: 10.1186/s12889-025-22142-3

Abstract: Complex public health problems have been addressed in communities through systems thinking and participatory methods like Group Model Building (GMB) and Causal Loop Diagrams (CLDs) albeit with some challenges. This study aimed to explore the… read more here.
