Construction and classification of novel BPS Wilson loops in quiver Chern–Simons-matter theories

Nuclear Physics B, 2016
In this paper we construct and classify novel Drukker–Trancanelli (DT) type BPS Wilson loops along infinite straight lines and circles in N=2,3 quiver superconformal Chern–Simons-matter theories, Aharony–Bergman–Jafferis–Maldacena (ABJM) theory, and N=4 ...

Next-to-leading power threshold effects for inclusive and exclusive processes with final state jets

Journal of High Energy Physics, 2020
It is well known that cross-sections in perturbative QCD receive large corrections from soft and collinear radiation, which can be resummed to all orders in the coupling.

Novel BPS Wilson loops in three-dimensional quiver Chern–Simons-matter theories

Physics Letters B, 2016
We show that generic three-dimensional N=2 quiver super Chern–Simons-matter theories admit Bogomol'nyi–Prasad–Sommerfield (BPS) Drukker–Trancanelli (DT) type Wilson loops.

The μ-τ reflection symmetry of Dirac neutrinos and its breaking effect via quantum corrections

Journal of High Energy Physics, 2017
Given the Dirac neutrino mass term, we explore the constraint conditions which allow the corresponding mass matrix to be invariant under the μ-τ reflection transformation, leading us to the phenomenologically favored predictions θ 23 = π/4 and δ = 3π/2 ...

Muon (g − 2) and flavor puzzles in the U(1) X -gauged leptoquark model

Journal of High Energy Physics, 2022
We present an economical model where an S 1 leptoquark and an anomaly-free U(1) X gauge symmetry with X = B 3 − 2L μ /3 − L τ /3 are introduced, to account for the muon anomalous magnetic moment a μ ≡ (g μ − 2) and flavor puzzles including R K ∗ $$ {R}_ ...

Study of the strong coupling constants, α_s (q² ) of π- and K⁰ mesons from π^-+p and π^-+C interactions at 40 GeV/c

Proceedings of the Mongolian Academy of Sciences
This paper is devoted to the production of π-and K0 mesons from π-+p→π-+X and π-+C→π-,K0+X interactions at 40 GeV/c as a function of the square of four momentum transfer. The cut parameter of the strong coupling constant is taken as Λac2=ma2+mc2.

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
