Stop search in SUSY SO(10) GUTs with nonuniversal Gaugino masses

We explore the stop mass and its possible probe through a set of three different signal processes within a class of SUSY GUTs with non-universal gaugino masses. The stop mass can be realized in a wide range (0.4–8 TeV) consistent with the current experimental constraints. We consider the decay processes; $$\tilde{t}_{1}\rightarrow t\tilde{\chi }_{1}^{0}$$ t ~ 1 → t χ ~ 1 0 , $$\tilde{t}_{1}\rightarrow b W^{\pm }\tilde{\chi }_{1}^{0}$$ t ~ 1 → b W ± χ ~ 1 0 and $$\tilde{t}_{1}\rightarrow b q{\bar{q}}^{\prime }\tilde{\chi }_{1}^{0}$$ t ~ 1 → b q q ¯ ′ χ ~ 1 0 to be possible signals, and explore the impact of the current experimental results as well as the possible mass scales of stop, which can be probed in the future collider experiments. We find that the first and third signal processes can be tested in the current experiments, and significantly probed in future, while the second signal process is not available for the current experiments in this class of SUSY GUTs. We also comment that the second signal process can be available to be tested when the collider experiments are conducted at high center of mass energies and luminosity.

Country images and identities in times of populism: Swiss media discourses on the ‘stop mass immigration’ initiative

The construction of certain country images and identities is traditionally studied in relation to public diplomacy, strategic communication and nation branding practices of state and non-state actors. However, we notice the increased instrumentalization of country images and identities in debates on issues beyond strategic promotional practices, such as those articulated around elections, referendums or migration. We analyse how Swiss media constructed Switzerland's image and identity in the debate following the 2014 referendum on ‘stop mass immigration’ initiative, in times of populism, a communication phenomenon and ideology discursively articulated by political and media actors. Thus, we: (1) bridge streams of research on country images, identities, migration and populism that have yet to be integrated; (2) propose critical discourse analysis to identify specific discursive strategies (offering insights into alternative methodologies for studying populist political communication content and style); (3) highlight the role of media in reproducing populist discourses on country images and identities.
