α′-corrected black holes in String Theory [PDF]
Journal of High Energy Physics, 2018 Abstract We consider the well-known solution of the Heterotic Superstring effective action to zeroth order in α ′ that describes the intersection of a fundamental string with momentum and a solitonic 5-brane and which gives a 3-charge, static, extremal, supersymmetric black hole in 5 dimensions upon dimensional ...

The quark mass correction to the string potential [PDF]
The European Physical Journal C, 1999 Following recent work by Lambiase and Nesterenko we study in detail the interquark potential for a Nambu-Goto string with point masses attached to its ends. We obtain exact solutions to the gap equations for the Lagrange multipliers and metric components and determine the potential without simplifying assumptions. We also discuss Lüscher term and argue

Quark mass correction to the string potential [PDF]
Physical Review D, 1996 A consistent method for calculating the interquark potential generated by the relativistic string with massive ends is proposed. In this approach the interquark potential in the model of the Nambu--Goto string with point--like masses at its ends is calculated.

Ringing and echoes from black bounces surrounded by the string cloud
European Physical Journal C: Particles and Fields, 2023 In the string theory, the fundamental blocks of nature are not particles but one-dimensional strings. Therefore, a generalization of this idea is to think of it as a cloud of strings. Rodrigues et al.

PROBLEMS OF MEASURING OF MOTION PARAMETERS OF THE DRILL STRING
Известия высших учебных заведений: Нефть и газ, 2017 The current methods of measuring of parameters of the movement of the drill string are reviewed. The as-sessment of these methods from the point of view of metrology and the effectiveness of the application of measuring equipment is given.

String loop corrections to the universal hypermultiplet [PDF]
Classical and Quantum Gravity, 2003 We study loop corrections to the universal dilaton supermultiplet for type IIA strings compactified on Calabi-Yau threefolds. We show that the corresponding quaternionic kinetic terms receive non-trivial one-loop contributions proportional to the Euler number of the Calabi-Yau manifold, while the higher-loop corrections can be absorbed by field ...

The first α′-correction to homogeneous Yang-Baxter deformations using O(d, d)
Journal of High Energy Physics, 2020 We use the O(d, d)-covariant formulation of supergravity familiar from Double Field Theory to find the first α′-correction to (unimodular) homogeneous Yang-Baxter (YB) deformations of the bosonic string.

AdS4/CFT3 from weak to strong string coupling
Journal of High Energy Physics, 2020 We consider the four-point function of operators in the stress tensor multiplet of the U(N) k × U(N) −k ABJM theory, in the limit where N is taken to infinity while N/k 5 is held fixed.

Monopoles on string-like models and the Coulomb's law
Physics Letters B, 2018 The monopole mass can be substantially altered, in the string-like braneworld setup, and can be employed in order to constrain the brane thickness limit.
