Minimal anomalous U(1) theories and collider phenomenology / Ekstedt, Andreas ; Enberg, Rikard ; Ingelman, Gunnar ; Löfgren, Johan ; et al
We study the collider phenomenology of a neutral gauge boson Z ′ arising in minimal but anomalous U(1) extensions of the Standard Model (SM). [...]

Complex Langevin analysis of the spontaneous symmetry breaking in dimensionally reduced super Yang-Mills models / Anagnostopoulos, Konstantinos ; Azuma, Takehiro ; Ito, Yuta ; Nishimura, Jun ; et al
In recent years the complex Langevin method (CLM) has proven a powerful method in studying statistical systems which suffer from the sign problem. [...]

2d orbifolds with exotic supersymmetry / Florakis, Ioannis ; García-Etxebarria, Iñaki ; Lüst, Dieter ; Regalado, Diego
We analyse various two dimensional theories arising from compactification of type II and heterotic string theory on asymmetric orbifolds. [...]

Anisotropic D3-D5 black holes with unquenched flavors / Penín, José ; Ramallo, Alfonso ; Zoakos, Dimitrios
We construct a black hole geometry generated by the intersection of N c color D3- branes and N f flavor D5-branes along a 2+1 dimensional subspace. [...]

Perturbative reduction of derivative order in EFT / Glavan, Dražen
Higher derivative corrections are ubiquitous in effective field theories, which seemingly introduces new degrees of freedom at successive orders. [...]

Fermionic Glauber operators and quark reggeization / Moult, Ian ; Solon, Mikhail ; Stewart, Iain ; Vita, Gherardo
We derive, in the framework of soft-collinear effective field theory (SCET), a Lagrangian describing the t -channel exchange of Glauber quarks in the Regge limit. [...]

Universal bounds on operator dimensions from the average null energy condition / Córdova, Clay ; Diab, Kenan
We show that the average null energy condition implies novel lower bounds on the scaling dimensions of highly-chiral primary operators in four-dimensional conformal field theories. [...]

Inflation in random landscapes with two energy scales / Blanco-Pillado, Jose ; Vilenkin, Alexander ; Yamada, Masaki
We investigate inflation in a multi-dimensional landscape with a hierarchy of energy scales, motivated by the string theory, where the energy scale of Kahler moduli is usually assumed to be much lower than that of complex structure moduli and dilaton field. [...]

Zero-range effective field theory for resonant wino dark matter. Part II. Coulomb resummation / Braaten, Eric ; Johnson, Evan ; Zhang, Hong
Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective field theory (ZREFT) in which the winos interact nonperturbatively through a contact interaction and charged winos also have electromagnetic interactions.

Orientifolds and duality cascades: confinement before the wall / Argurio, Riccardo ; Bertolini, Matteo
We consider D-branes at orientifold singularities and discuss two properties of the corresponding low energy four-dimensional effective theories which are not shared, generically, by other Calabi-Yau singularities. [...]
