Quark-antiquark potential in defect conformal field theory
Michelangelo Preti, Diego Trancanelli, Edoardo Vescovi
We consider antiparallel Wilson lines in N=4 super Yang-Mills in the presence of a codimension-1 defect. We compute the Wilson lines' expectation value both at weak coupling, in th…
H ortho-to-para conversion on grains: A route to fast deuterium fractionation in dense cloud cores?
Stefano Bovino, Tommaso Grassi, Dominik R. Schleicher +1
Deuterium fractionation, i.e. the enhancement of deuterated species with respect to the non-deuterated ones, is considered to be a reliable chemical clock of star-forming regions.…
Impact of the heavy quark matching scales in PDF fits
The xFitter Developers Team, V. Bertone, D. Britzger +14
We investigate the impact of displaced heavy quark matching scales in a global fit. The heavy quark matching scale determines at which energy scale the QCD theory trans…
Wilson lines as superconformal defects in ABJM theory: a formula for the emitted radiation
Lorenzo Bianchi, Luca Griguolo, Michelangelo Preti +1
We study operator insertions into 1/2 BPS Wilson loops in N = 6 ABJM theory and investigate their two-point correlators. In this framework, the energy emitted by a heavy moving pro…
Towards the exact Bremsstrahlung function of ABJM theory
Marco S. Bianchi, Luca Griguolo, Andrea Mauri +3
We present the three-loop calculation of the Bremsstrahlung function associated to the 1/2-BPS cusp in ABJM theory, including color subleading corrections. Using the BPS condition…
Running of the Charm-Quark Mass from HERA Deep-Inelastic Scattering Data
A. Gizhko, A. Geiser, S. Moch +47
Combined HERA data on charm production in deep-inelastic scattering have previously been used to determine the charm-quark running mass in the MSbar renormalisation sche…
