Baryons and Confining Strings
نویسندگان
چکیده
The potential of three heavy quarks has recently been the object of detailed numerical studies [1,2], which lend support to the so-called Y law, inspired by a string picture of heavy baryons. Here, we study the leading effect of string fluctuations on the potential, the analogue of the Lüscher term [3,4,5] in the quark-antiquark potential. Understanding such corrections to the Y law is particularly important since the transition from ∆ to Y law occurs at large quark separations [1].

Deforming baryons into confining strings
We find explicit probe D3-brane solutions in the infrared of the Maldacena-Nuñez background. The solutions describe deformed baryon vertices: q external quarks are separated in spacetime from the remaining N − q. As the separation is taken to infinity we recover known solutions describing infinite confining strings in N = 1 gauge theory. We present results for the mass of finite confining strin...
متن کامل3d Georgi–glashow Model and Confining Strings at Zero and Finite Temperatures
In this review, we discuss the confining and finite-temperature properties of the 3D SU(N) Georgi–Glashow model, and of 4D compact QED. At zero temperature, we derive string representations of both theories, thus constructing the SU(N) version of Polyakov’s theory of confining strings. We discuss the geometric properties of confining strings, as well as the appearance of the string θ term from ...
متن کاملUniversality Class of Confining Strings
A recently proposed model of confining strings has a non-local world-sheet action induced by a space-time Kalb-Ramond tensor field. Here we show that, in the large-D approximation, an infinite set of ghostand tachyon-free truncations of the derivative expansion of this action all lead to c = 1 models. Their infrared limit describes smooth strings with world-sheets of Hausdorff dimension DH = 2 ...
متن کاملConfining Strings at High Temperature
We show that the high-temperature behaviour of the recently proposed confining strings reproduces exactly the correct large-N QCD result, for a large class of trun-cations of the long-range interaction between surface elements.
متن کاملConfining Strings with Topological Term
We consider several aspects of ‘confining strings’, recently proposed to describe the confining phase of gauge field theories. We perform the exact duality transformation that leads to the confining string action and show that it reduces to the Polyakov action in the semiclassical approximation. In 4D we introduce a ‘θ-term’ and compute the low-energy effective action for the confining string i...
