Constraints on anomalous QGC's in e+e−e^{+}e^{-} interactions from 183 to 209 GeV

The acoplanar photon pairs produced in the reaction e(+) e(-) - → vvyy are analysed in the 700 pb(-1) of data collected by the ALEPH detector at centre-of-mass energies between 183 and 209 GeV. No deviation from the Standard Model predictions is seen in any of the distributions examined. The resulting 95% C.L. limits set on anomalous QGCs, a(0)(Z), a(c)(Z), a(0)(W) and a(c)(W), are -0.012 lt a(0)(Z)/Lambda(2) lt +0.019 GeV-2, -0.041 lt a(c)(Z)/Lambda(2) lt +0.044 GeV-2, -0.060 lt a(0)(W)/Lambda(2) lt +0.055 GeV-2, -0.099 lt a(c)(W)/Lambda(2) lt +0.093 GeV-2, where Lambda is the energy scale of the new physics responsible for the anomalous couplings

Co-branding as a masstige strategy for luxury brands : desirable or not?

Co-branding is a popular brand leveraging strategy, widely regarded as beneficial to allied brands. Despite its popularity in practice, there is a paucity of research on co-branding strategies in masstige marketing and luxury branding. Employing a quantitative research design via two survey-based experiments we examine the viability of co-branding versus downward extension on luxury consumers’ attitudes and purchase intent. Underpinned by Categorization and Information Integration theories, we find co-branding to be the more desirable masstige strategy in eliciting favorable consumer responses. Further, we show that co-branding is not detrimental to the prestige and desirability of the luxury brand partner, thus countering the narrative that democratization of luxury dilutes luxury brands’ appeal. Our research advances knowledge on luxury consumers’ evaluations of competing masstige strategies, the mechanisms underlying such evaluations, and the spillover effect of co-branding on luxury brands. We offer actionable implications for luxury brand managers desiring to expand into mass prestige markets
