A uniqueness theorem for warped N  > 16 Minkowski backgrounds with fluxes / Lautz, S. ; Papadopoulos, G.
We demonstrate that warped Minkowski space backgrounds, Rn−1,1×wMd−n , n≥3 , that preserve strictly more than 16 supersymmetries in d=11 and type II d=10 supergravities and with fields which may not be smooth everywhere are locally isometric to the Rd−1,1 Minkowski vacuum. [...]

On some implications of the BaBar data on the γ ⁎ η ′ transition form factor / Kroll, P. ; Passek-Kumerički, K.
At leading-twist accuracy the form factors for the transitions from a virtual photon to the η or η′ can be expanded into a power series of the variable ω , being related to the difference of the two photon virtualities. [...]

Anatomy of the newly observed hidden-charm pentaquark states: P c (4312), P c (4440) and P c (4457) / Guo, Zhi-Hui ; Oller, J.A.
We study the newly reported hidden-charm pentaquark candidates Pc(4312) , Pc(4440) and Pc(4457) from the LHCb Collaboration, in the framework of the effective-range expansion and resonance compositeness relations. [...]

Next-to-leading-order predictions for single vector-like quark production at the LHC / Cacciapaglia, Giacomo ; Carvalho, Alexandra ; Deandrea, Aldo ; Flacke, Thomas ; et al
We propose simulation strategies for single production of third generation vector-like quarks at the LHC, implementing next-to-leading-order corrections in QCD and studying in detail their effect on cross sections and differential distributions. [...]
