Threshold resummation of new partonic channels at next-to-leading power / van Beekveld, Melissa (Oxford U., Theor. Phys.) ; Vernazza, Leonardo (INFN, Turin ; CERN) ; White, Chris D. (Queen Mary, U. of London)
Collider observables involving heavy particles are subject to large logarithmic terms near threshold, which must be summed to all orders in perturbation theory to obtain sensible results. [...]

Comment on "More Axions from Strings'' / Hindmarsh, Mark (U. Helsinki (main) ; CERN ; Helsinki U. ; Sussex U. ; Birmingham U.) ; Lizarraga, Joanes (Basque U., Bilbao) ; Lopez-Eiguren, Asier (Tufts U.) ; Urrestilla, Jon (Basque U., Bilbao)
We comment on a claim that axion strings show a long-term logarithmic increase in the number of Hubble lengths per Hubble volume [arXiv:2007.04990], thereby violating the standard "scaling" expectation of an O(1) constant. [...]

Angular correlations of heavy-flavour hadron decay electrons and charged particles in pp collisions at $\sqrt{s}$ = 5.02 TeV with ALICE at the LHC / Singh, Ravindra (Indian Inst. Tech., Indore)
Two-particle azimuthal correlations of electrons from heavy-flavour hadron decays with charged particles can give insight into the properties of heavy-quark production and hadronization into heavy-flavour jets.\\ In this contribution, the ALICE results measured in pp collisions at 5.02 TeV, collected in the LHC Run 2, are presented.

Heavy flavor collectivity in small systems / Krintiras, Georgios Konstantinos
The presence of correlations between particles significantly separated in pseudorapidity in proton-proton and proton-nucleus collisions revealed surprises in the early LHC data. [...]

Measurement of the $c$-jet mistagging efficiency in $t\bar{t}$ events using $pp$ collision data at $\sqrt{s}=13$ TeV collected with the ATLAS detector
A technique is presented to measure the efficiency with which $c$-jets are mistagged as b-jets (mistagging efficiency) using $t\bar{t}$ events, where one of the $W$ bosons decays into an electron or muon and a neutrino and the other decays into a quark-antiquark pair. [...]

An Altarelli Cocktail for the MiniBooNE Anomaly? / Brdar, Vedran (Fermilab ; Northwestern U.) ; Kopp, Joachim (CERN ; Mainz U., Inst. Phys.)
We critically examine a number of theoretical uncertainties affecting the MiniBooNE short-baseline neutrino oscillation experiment in an attempt to better understand the observed excess of electron-like events [...]
