Effective lagrangian for a mass dimension one fermionic field in curved spacetime / Bueno Rogerio, R.J. ; Hoff da Silva, J.M. ; Dias, M. ; Pereira, S.H.
In this work we use momentum-space techniques to evaluate the propagator G ( x, x ′ ) for a spin 1 / 2 mass dimension one spinor field on a curved Friedmann-Robertson-Walker spacetime. [...]

6d string chains / Gadde, Abhijit ; Haghighat, Babak ; Kim, Joonho ; Kim, Seok ; et al
We consider bound states of strings which arise in 6d (1,0) SCFTs that are realized in F-theory in terms of linear chains of spheres with negative self-intersections 1,2, and 4. [...]

Flow equation of N $$ \mathcal{N} $$ = 1 supersymmetric O ( N ) nonlinear sigma model in two dimensions / Aoki, Sinya ; Kikuchi, Kengo ; Onogi, Tetsuya
We study the flow equation for the N $$ \mathcal{N} $$ = 1 supersymmetric O ( N ) nonlinear sigma model in two dimensions, which cannot be given by the gradient of the action, as evident from dimensional analysis. [...]

Non-resonant and electroweak NNLO correction to the e + e − top anti-top threshold / Beneke, M. ; Maier, A. ; Rauh, T. ; Ruiz-Femenía, P.
We determine the NNLO electroweak correction to the e + e − → b b ¯ W + W − X $$ {e}^{+}{e}^{-}\to b\overline{b}{W}^{+}{W}^{-}X $$ production cross section near the top-pair production threshold. [...]

Tidal stresses and energy gaps in microstate geometries / Tyukov, Alexander ; Walker, Robert ; Warner, Nicholas
We compute energy gaps and study infalling massive geodesic probes in the new families of scaling, microstate geometries that have been constructed recently and for which the holographic duals are known. [...]
