Interactions between several types of cosmic strings
Journal of High Energy Physics, 2023 We study the interaction of several types of static straight cosmic strings, including local strings, global strings, and bosonic superconducting strings with and without magnetic currents.

Tensionless strings and Killing(-Yano) tensors
Physics Letters B, 2022 We construct invariants for bosonic and spinning tensionless (null) strings in backgrounds that carry Killing tensors or Killing-Yano tensors of mixed type. This is facilitated by the close relation of these strings to point particles.

Conformal to harmonic gauge for bosonic strings [PDF]
Europhysics letters, 2018 We consider the Polyakov theory of bosonic strings in conformal gauge which are used to study the conformal anomaly. However, it exhibits ghost number anomaly.

The scattering amplitude of stringy hadrons: strings with opposite charges on their endpoints
Journal of High Energy Physics, 2020 In this note we describe hadrons: mesons and baryons as strings with electric charges on their endpoints. We consider here only the neutral system with opposite charges, coupled to an external constant electromagnetic field.

Open string pair production from the interacting dressed-angled D-strings
European Physical Journal C: Particles and Fields, 2023 We calculate the rate of the open string pair production from the interaction of two non-intersecting D-strings at angle. The D-strings have been equipped with the U(1) gauge potentials in the presence of the Kalb–Ramond field.

On the quantization of folded strings in non-critical dimensions
Journal of High Energy Physics, 2020 Classical rotating closed string are folded strings. At the folding points the scalar curvature associated with the induced metric diverges. As a consequence one cannot properly quantize the fluctuations around the classical solution since there is no ...

Bosonic sectorized strings and the (DF)2 theory [PDF]
Journal of High Energy Physics, 2019 In this work, we investigate the bosonic chiral string in the sectorized inter- pretation, computing its spectrum, kinetic action and 3-point amplitudes. As expected, the bosonic ambitwistor string is recovered in the tensionless limit.

Fundamental membranes and the string dilaton
Journal of High Energy Physics, 2022 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 kinematic ...

Degeneracy Between the Regge Slope of Mesons and Baryons from Supersymmetry [PDF]
, 2009 We consider the degeneracy between the Regge slope of mesons and baryons in QCD. We argue that within the "orientifold large-N approximation" asymptotically massive mesons and baryons become supersymmetric partners and hence degenerate.

Quantizing the rotating string with massive endpoints
Journal of High Energy Physics, 2018 We compute leading order quantum corrections to the Regge trajectory of a rotating string with massive endpoints using semiclassical methods. We expand the bosonic string action around a classical rotating solution to quadratic order in the fluctuations ...
