(Non-)Decoupled Supersymmetric Field Theories [PDF]

, 2014
We study some consequences of coupling supersymmetric theories to (super)gravity. To linear order, the couplings are determined by the energy-momentum supermultiplet.

Rotating kinky braneworlds

Journal of High Energy Physics, 2018
Cylindrical braneworlds have been used in the literature as a convenient way to resolve co-dimension-two branes. They are prevented from collapsing by a massless worldvolume field with non-trivial winding, but here we discuss another way of preventing ...

Chameleon field theories [PDF]

Classical and Quantum Gravity, 2013
Chameleons are light scalar fields with remarkable properties. Through the interplay of self-interactions and coupling to matter, chameleon particles have a mass that depends on the ambient matter density. The manifestation of the fifth force mediated by chameleons therefore depends sensitively on their environment, which makes for a rich phenomenology.

Bootstrapping massive quantum field theories

Journal of High Energy Physics, 2020
We propose a new non-perturbative method for studying UV complete unitary quantum field theories (QFTs) with a mass gap in general number of spacetime dimensions.

T T ¯ $$ T\overline{T} $$ deformations and the width of fundamental particles

Journal of High Energy Physics, 2022
We provide a simple geometric meaning for deformations of so-called T T ¯ $$ T\overline{T} $$ type in relativistic and non-relativistic systems. Deformations by the cross products of energy and momentum currents in integrable quantum field theories are ...

The impact of rule updates on the performance of racewalkers and the classification of countries: An analysis at the Olympic Games

Sport TK
Numerous controversies arose over the judgment of the racewalking events, and the rules were amended more than once. Before 1995, the rule required constant touch with the ground, and the need for a straight knee was only applied in the upright vertical

Effective Field Theories and Inflation [PDF]

, 2003
We investigate the possible influence of very-high-energy physics on inflationary predictions focussing on whether effective field theories can allow effects which are parametrically larger than order H^2/M^2, where M is the scale of heavy physics and H ...

Inverse bootstrapping conformal field theories

Journal of High Energy Physics, 2018
We propose a novel approach to study conformal field theories (CFTs) in general dimensions. In the conformal bootstrap program, one usually searches for consistent CFT data that satisfy crossing symmetry.

Field theories on null manifolds

Journal of High Energy Physics, 2020
We argue that generic field theories defined on null manifolds should have an emergent BMS or conformal Carrollian structure. We then focus on a simple interacting conformal Carrollian theory, viz. Carrollian scalar electrodynamics.

Topological conformal field theories and gauge theories

, 2006
This paper gives a construction, using heat kernels, of differential forms on the moduli space of metrised ribbon graphs, or equivalently on the moduli space of Riemann surfaces with boundary.
