No classical (anti)de Sitter solutions with O8planes
/ Cribiori, Niccolò ; Junghans, Daniel
It was recently proposed that type IIA string theory may allow classical de Sitter solutions with O8planes as the only localized sources. [...]

Kaluza–Klein reduction on a maximally nonRiemannian space is modulifree
/ Cho, Kyoungho ; Morand, Kevin ; Park, JeongHyuck
We propose a novel Kaluza–Klein scheme which assumes the internal space to be maximally nonRiemannian, meaning that no Riemannian metric can be defined for any subspace. [...]

New high precision study on the decay width of the Hoyle state in 12 C
/ Rana, T.K. ; Bhattacharya, S. ; Bhattacharya, C. ; Manna, S. ; et al
Precise estimation of the rare direct 3 α decay of the Hoyle state of 12 C has been made to unveil its unusual α cluster configurations ranging from linear 3 α chain structure to diffuse Bose gas as well as Bose Einstein condensate. [...]

Black hole evaporation in conformal (Weyl) gravity
/ Xu, Hao ; Yung, ManHong
In this work, we explore all possible scenarios in the evaporation process of a spherical neutral AdS black hole in fourdimensional conformal gravity, where the equations of states are branched. [...]

Holographic entanglement negativity conjecture for adjacent intervals in AdS 3 /CFT 2
/ Jain, Parul ; Malvimat, Vinay ; Mondal, Sayid ; Sengupta, Gautam
We propose a holographic entanglement negativity conjecture involving the bulk geometry, for mixed states of adjacent intervals in (1+1) dimensional dual conformal field theories through the AdS/CFT correspondence. [...]

On exclusive Racah matrices S¯ for rectangular representations
/ Morozov, A.
We elaborate on the recent observation that evolution for twist knots simplifies when described in terms of triangular evolution matrix B , not just its eigenvalues Λ, and provide a universal formula for B , applicable to arbitrary rectangular representation R=[rs] . [...]

Charmquark Yukawa coupling in h→cc¯γ at LHC
/ Han, Tao ; Nachman, Benjamin ; Wang, Xing
It is extremely challenging to probe the charmquark Yukawa coupling at hadron colliders primarily due to the large Standard Model (SM) background (including h→bb¯ ) and the lack of an effective trigger for the signal h→cc¯ . [...]
