The Spectrum of a Binding System for a Heavy Quark with an Anti-Sbottom or for a Sbottom and Anti-Sbottom Pair

Since long-lived light bottom squark (sbottom) and its anti-particle with a mass close to the bottom quark have not been excluded by experiments so far, we consider such a sbottom to combine with its anti-particle to form a color singlet meson-like bound state or to combine with a common anti-quark to form a fermion-like one, or accordingly their anti-particles to form an anti-particle bound system. Namely we calculate the low-lying spectrum of the systems based on QCD inspired potential model. To be as relativistic as possible, we start with the framework of Bethe-Salpeter (BS) equation even for non-relativistic binding systems. Finally, we obtain the requested spectrum by constructing general forms of the BS wave functions and solving the BS equations under instantaneous approximation.Comment: 13 pages, 1 figur

A Resource Depletion Spiral? A Moderated Mediation Model of Emotional Exhaustion and Venting at Work

We investigate whether, why, and when emotionally exhausted employees may engage in venting, or discharging negative feelings to others at work. Drawing on emotion regulation research, we envision that emotionally exhausted employees engage in response-focused emotion regulation, which depletes regulatory resources and leads to emotion regulation failures (i.e., venting). We further examine employees’ core self-evaluation and turnover intention as boundary conditions for different stages of the mediated relationship. Moderated mediation analysis suggests that emotional exhaustion is positively related to venting only among employees with low core self-evaluation who reluctantly stay in organizations. Implications for research and practice are discussed
