Accidental Peccei–Quinn symmetry from discrete flavour symmetry and Pati–Salam

Physics Letters B, 2018
We show how an accidental U(1) Peccei–Quinn (PQ) symmetry can arise from a discrete A4 family symmetry combined with a discrete flavour symmetry Z3×Z52, in a realistic Pati–Salam unified theory of flavour. Imposing only these discrete flavour symmetries,

Farmers' Preferences for Fossil‐Free Mineral Nitrogen Fertilizers: Role of Prices, Climate, Production Origin, and Identity

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Disruptions in global fertilizer markets and climate targets have increased interest in fossil‐free mineral nitrogen fertilizers. This study examines farmers' preferences for conventional (fossil‐based) and fossil‐free fertilizers using a labeled discrete choice experiment with 211 Swedish farmers.

One sum to rule them all: a second order master rate sum rule for charm decays

Journal of High Energy Physics
We show that within the Standard Model any system of hadronic weak charm decays related by U-spin satisfies the following rate sum rule: sum of CF and DCS CKM − free rates sum of SCS CKM − free rates = 1 , $$ \frac{\left(\mathrm{sum}\ \mathrm{of ...

Constraining multi-Higgs flavour models [PDF]

, 2014
peer reviewedTo study a flavour model with a non-minimal Higgs sector one must first define the symmetries of the fields; then identify what types of vacua exist and how they may break the symmetries; and finally determine whether the remnant symmetries ...

Return and Volatility Spillovers Among Major Cotton Markets

Agribusiness, EarlyView.
ABSTRACT This study explores return and volatility transmission among major cotton markets. Several events have disrupted cotton supply and demand in recent years, leading to heightened price volatility and significant shifts in market interconnections.

Video and Text‐Based Supplemental Health Information and Consumer Willingness to Pay for Nutrient‐Enhanced Eggs

Agribusiness, EarlyView.
ABSTRACT Nutritional information is very important in the food choices of consumers. However, when they are too scientific or technical, they have the potential to confuse consumers, resulting in information asymmetry and dissuading them from making beneficial choices.

The flavour puzzle and flavour symmetries

, 2017
The presence of approximate flavour symmetries is invoked to make New Physics models near the TeV scale compatible with the very demanding quark flavour violation tests. These tests pose a serious threat for any acceptable Standard Model extension at the

Dynamical versus variational symmetries: understanding Noether's first theorem [PDF]

, 2004
It is argued that awareness of the distinction between dynamical and variational symmetries is crucial to understanding the significance of Noether's 1918 work.

Consumer Demand and Market Response to Added Sugar Labeling: Evidence From the Updated Nutrition Facts Panel

Agribusiness, EarlyView.
ABSTRACT This paper examines how mandatory disclosure of added sugar content on the updated U.S. Nutrition Facts Panel (NFP) affects consumer demand and market outcomes. Using NielsenIQ Retail Scanner Data (2015–2020) and a random coefficient discrete choice model, we estimate how added sugar labeling influences purchasing behavior in yogurt and cookie

More about quark Yukawa textures from selection rules without group actions

Journal of High Energy Physics
We study the coupling selection rules associated with non-group symmetries, i.e., ℤ2 gauging of ℤ M symmetries. We clarify which Yukawa textures can be derived by our selection rules for M = 3, 4, and 5, and obtain various textures including the nearest ...
