Calculations of Inflaton Decays and Reheating: with Applications to No-Scale Inflation Models / Ellis, John ; Garcia, Marcos A G ; Nanopoulos, Dimitri V ; Olive, Keith A
We discuss inflaton decays and reheating in no-scale Starobinsky-like models of inflation, calculating the effective equation-of-state parameter, $w$, during the epoch of inflaton decay, the reheating temperature, $T_{\rm reh}$, and the number of inflationary e-folds, $N_*$, comparing analytical approximations with numerical calculations.

Instanton Operators and the Higgs Branch at Infinite Coupling / Cremonesi, Stefano ; Ferlito, Giulia ; Hanany, Amihay ; Mekareeya, Noppadol
The richness of 5d $\mathcal{N}=1$ theories with a UV fixed point at infinite coupling is due to the existence of local disorder operators known as instanton operators. [...]

Consistent truncations of M-theory for general SU(2) structures / Triendl, Hagen
In seven dimensions any spin manifold admits an SU(2) structure and therefore very general M-theory compactifications have the potential to allow for a reduction to N=4 gauged supergravity. [...]

A comparison of updating algorithms for large N reduced models / Pérez, Margarita García ; González-Arroyo, Antonio ; Keegan, Liam ; Okawa, Masanori ; Ramos, Alberto
We investigate Monte Carlo updating algorithms for simulating $SU(N)$ Yang-Mills fields on a single-site lattice, such as for the Twisted Eguchi-Kawai model (TEK). [...]

Collider Interplay for Supersymmetry, Higgs and Dark Matter / Buchmueller, O (Imperial Coll., London) ; Citron, M (Imperial Coll., London) ; Ellis, J (King's Coll. London ; CERN) ; Guha, S (CERN ; Birla Inst. Tech. Sci.) ; Marrouche, J (Imperial Coll., London) ; Olive, K A (Minnesota U., Theor. Phys. Inst.) ; de Vries, K (Imperial Coll., London) ; Zheng, Jiaming (Minnesota U., Theor. Phys. Inst.)
We discuss the potential impacts on the CMSSM of future LHC runs and possible electron-positron and higher-energy proton-proton colliders, considering searches for supersymmetry via MET events, precision electroweak physics, Higgs measurements and dark matter searches. [...]

T-duality, Quotients and Currents for Non-Geometric Closed Strings / Bakas, Ioannis (Natl. Tech. U., Athens) ; Lust, Dieter (Munich, Max Planck Inst. ; Munich U., ASC ; CERN)
We use the canonical description of T-duality as well as the formulation of T-duality in terms of chiral currents to investigate the geometric and non-geometric faces of closed string backgrounds originating from principal torus bundles with constant H-flux. [...]
