Generalized ’t Hooft anomalies on non-spin manifolds (2020)
Journal Article
Anber, M. M., & Poppitz, E. (2020). Generalized ’t Hooft anomalies on non-spin manifolds. Journal of High Energy Physics, 2020(4), Article 97. https://doi.org/10.1007/jhep04%282020%29097

We study the mixed anomaly between the discrete chiral symmetry and general baryon-color-flavor (BCF) backgrounds in SU(Nc) gauge theories with Nf flavors of Dirac fermions in representations ℛc of N -ality nc, formulated on non-spin manifolds. We sh... Read More about Generalized ’t Hooft anomalies on non-spin manifolds.

Type-B anomaly matching and the 6D (2,0) theory (2020)
Journal Article
Niarchos, V., Papageorgakis, C., & Pomoni, E. (2020). Type-B anomaly matching and the 6D (2,0) theory. Journal of High Energy Physics, 2020(4), Article 48. https://doi.org/10.1007/jhep04%282020%29048

We study type-B conformal anomalies associated with 12 -BPS Coulomb-branch operators in 4D N = 2 superconformal field theories. When the vacuum preserves the conformal symmetry these anomalies coincide with the two-point function coefficients in the... Read More about Type-B anomaly matching and the 6D (2,0) theory.

An effective equidistribution result for SL(2,R)\ltimes (R^2)^{oplus k} and application to inhomogeneous quadratic forms (2020)
Journal Article
Strombergsson, A., & Vishe, P. (2020). An effective equidistribution result for SL(2,R)\ltimes (R^2)^{oplus k} and application to inhomogeneous quadratic forms. Journal of the London Mathematical Society, 102(1), 143-204. https://doi.org/10.1112/jlms.12316

Let G = SL(2, R) (R2) ⊕k and let Γ be a congruence subgroup of SL(2, Z) (Z2) ⊕k. We prove a polynomially effective asymptotic equidistribution result for special types of unipotent orbits in Γ\G which project to pieces of closed horocycles in SL(2, Z...

One-loop amplitudes in AdS5×S5 supergravity from N = 4 SYM at strong coupling (2020)
Journal Article
Aprile, F., Drummond, J., Heslop, P., & Paul, H. (2020). One-loop amplitudes in AdS5×S5 supergravity from N = 4 SYM at strong coupling. Journal of High Energy Physics, 2020(3), Article 190. https://doi.org/10.1007/jhep03%282020%29190

We explore the structure of maximally supersymmetric Yang-Mills correlators in the supergravity regime. We develop an algorithm to construct one-loop supergravity amplitudes of four arbitrary Kaluza-Klein supergravity states, properly dualised into s...

Positive Ricci curvature on simply-connected manifolds with cohomogeneity-two torus actions (2020)
Journal Article
Corro, D., & Galaz-García, F. (2020). Positive Ricci curvature on simply-connected manifolds with cohomogeneity-two torus actions. Proceedings of the American Mathematical Society, 148(7), 3087-3097. https://doi.org/10.1090/proc/14961

We show that for each n 1, there exist infinitely many spin and non-spin diffeomorphism types of closed, smooth, simply-connected (n + 4)- manifolds with a smooth, effective action of a torus T n+2 and a metric of positive Ricci curvature invariant u...

Isolating the Odderon in central production in high energy pA and AA collisions (2020)
Journal Article
McNulty, R., Khoze, V., Martin, A., & Ryskin, M. (2020). Isolating the Odderon in central production in high energy pA and AA collisions. The European Physical Journal C, 80(3), Article 80. https://doi.org/10.1140/epjc/s10052-020-7846-5

We study the rapidity dependence of the central exclusive production cross sections of C-even mesons in pA and AA collisions, where A is a heavy ion. We observe qualitatively different behaviour of the contributions arising from γ-Odderon and Pomeron...

Torus actions on rationally elliptic manifolds (2020)
Journal Article
Galaz-García, F., Kerin, M., & Radeschi, M. (2021). Torus actions on rationally elliptic manifolds. Mathematische Zeitschrift, 297, 197-221. https://doi.org/10.1007/s00209-020-02508-6

An upper bound is obtained on the rank of a torus which can act smoothly and effectively on a smooth, closed (simply connected) rationally elliptic manifold. In the maximal-rank case, the manifolds admitting such actions are classified up to equivari... Read More about Torus actions on rationally elliptic manifolds.

Reliability analysis of phased mission systems when components can be swapped upon failure (2020)
Journal Article
Coolen, F., Huang, X., & Najem, A. (2020). Reliability analysis of phased mission systems when components can be swapped upon failure. ASCE-ASME Journal of Risk and Uncertainty in Engineering Systems, Part B: Mechanical Engineering, 6(2), Article 020905. https://doi.org/10.1115/1.4046328

This paper proposes a new strategy to improve the reliability of phased mission systems (PMS), namely, by swapping of components. In the proposed strategy, when a component fails, it can be swapped by another one in the system which is still function...

We study SU(Nc) gauge theories with Dirac fermions in representations ℛ of nonzero N -ality, coupled to axions.
