Modern reconstruction techniques can effectively model complex 3D scenes from sparse 2D views. However, automatically assessing the quality of novel views and identifying artifacts is challenging due to the lack of ground truth images and the limitat

Abstract We examine possible experimental signatures that may be exploited to search for stable supermassive particles with electric charges of $${{\mathcal {O}}}(1)$$ O ( 1 ) in future underground experiments, and the upcoming JUNO experiment in par

Abstract We study the quantization of the bosonic sector of supermembrane theory in double dimensional reduction, in order to extract the dependence of the resulting world-sheet action on the string dilaton (which cannot be obtained from a purely kin

Abstract We consider the Wheeler-DeWitt operator associated with the bosonic part of the Hamiltonian of D = 11 supergravity in a formulation with only the spatial components of the three-form and six-form fields, and compare it with the E10 Casimir o

Abstract We reconsider the supermembrane in a Minkowski background and in the light-cone gauge as a one-dimensional gauge theory of area preserving diffeomorphisms (APDs). Keeping the membrane tension T as an independent parameter we show that T is p

Abstract The involutory subalgebra K( e $$ \mathfrak{e} $$ 9) of the affine Kac-Moody algebra e $$ \mathfrak{e} $$ 9 was recently shown to admit an infinite sequence of unfaithful representations of ever increasing dimensions [1]. We revisit these re

Abstract Supersymmetric Yang-Mills theories can be characterized by a non-local and non-linear transformation of the bosonic fields (Nicolai map) mapping the interacting functional measure to that of a free theory, such that the Jacobi determinant of

Abstract Supersymmetric gauge theories are characterized by the existence of a transformation of the bosonic fields (Nicolai map) such that the Jacobi determinant of the transformation equals the product of the Matthews-Salam-Seiler and Faddeev-Popov

Abstract We compute the Kaluza-Klein spectrum of the non-supersymmetric SO(3) × SO(3)-invariant AdS4 vacuum of 11-dimensional supergravity, whose lowest-lying Kaluza-Klein modes belong to a consistent truncation to 4-dimensional N $$ \mathcal{N} $$

Building on the insight that primordial black holes can arise from the formation and subsequent gravitational collapse of bound states of stable supermassive elementary particles during the early radiation era, we offer a comprehensive picture descri
