The leading term for the energy of a bound state of k-quarks and k-antiquarks is proportional to its separation L. These k-string configurations have a Lüscher term associated with their quantum fluctuations which is typically a 1/L correction to the energy. We review the status of tensions and Lüscher terms in the context of lattice gauge theory,… (More)
We perform a systematic analysis of k-strings in the framework of the gauge/gravity correspondence. We discuss the Klebanov-Strassler supergravity background which is known to be dual to a confining supersymmetric gauge theory with chiral symmetry breaking. We obtain the k-string tension in agreement with expectations of field theory. Our main new result is… (More)

We construct an explicit and manifestly (1,0) heterotic sigma-model where the background fields are those of 10D, N = IIB supergravity.
Using a renormalization group method, we calculate 800 high-temperature coefficients of the magnetic susceptibility of the hierarchical Ising model. The conventional quantities obtained from differences of ratios of coefficients show unexpected smooth oscillations with a period growing logarithmically and can be fitted assuming corrections to the scaling… (More)
We provide world sheet non-supersymmetrical actions that describe the coupling of a bosonic string to the tachyon and massless states of both the type-B and type-O theories. The type-B theory is derived as a truncation and chiral doubling of the Ramond-Ramond sector in our previous model that connected the (1,0) heterotic string to a 10D, type-IIB… (More)

It has been reported that a large proportion of patients with major psychiatric disorders can recall a short story better if they listen with one ear rather than the other (monaural asymmetry), and that binaural performance is worse than with the better ear alone (binaural inferiority). Blocking the poorer ear with an earplug is said to significantly… (More)
