Quark System, Compact Pentaquark, and Gauge/String Duality (Part II)
Oleg Andreev
This is the second of two companion papers in which we continue to develop the construction of the doubly heavy pentaquark systems using the gauge/string duality. In this paper, we…
Towards a Stringy Description for the -Quark System
Oleg Andreev
For the case of two light flavors we propose the stringy description of the system made of one heavy and one light quark-antiquark pair, with the aim of exploring the two lower-lyi…
Investigation of two-photon 2s -> 1s decay in one-electron and one-muon ions
V. A. Knyazeva, K. N. Lyashchenko, M. Zhang +2
We have studied the radiative decay of the 2s state of one-electron and one-muon ions, where the two-photon mechanism plays an important role. Due to the nuclear size corrections t…
On the -Quark Potential in String Models
Oleg Andreev
We propose a string theory construction for the system of two heavy quarks and two light antiquarks. The potential of the system is a function of separation between the quarks. We…
Electron-loss-to-continuum cusp in collisions of U with N and Xe
P. -M. Hillenbrand, K. N. Lyashchenko, S. Hagmann +24
We study the electron-loss-to-continuum (ELC) cusp experimentally and theoretically by comparing the ionization of U projectiles in collisions with N and Xe targets, at…
String breaking in a cold wind as seen by string models
Oleg Andreev
Using the gauge/string duality, we model a heavy quark-antiquark pair in a color singlet state moving through a cold medium and explore the consequences of temperature and velocity…
