• #### Wilson line correlators beyond the large-Nc ﻿

(Journal article; Peer reviewed, 2021)
We study hard 1 → 2 final-state parton splittings in the medium, and put special emphasis on calculating the Wilson line correlators that appear in these calculations. As partons go through the medium their color continuously ...

(Journal article; Peer reviewed, 2021)
We report Magnetospheric Multiscale four-spacecraft observations of a thin reconnecting current sheet with weakly asymmetric inflow conditions and a guide field of approximately twice the reconnecting magnetic field. The ...
• #### Relationship Between Microbial Growth and Hydraulic Properties at the Sub-Pore Scale ﻿

(Journal article; Peer reviewed, 2021)
Accumulation of microbial biomass and its influence on porous media flow were investigated under saturated flow conditions. Microfluidic experiments were performed with model organisms, and their accumulation was observed ...
• #### Evolution of IMF By Induced Asymmetries: The Role of Tail Reconnection ﻿

(Journal article; Peer reviewed, 2021)
North-south asymmetries arise in the magnetosphere-ionosphere system when a significant east-west (By) component is present in the interplanetary magnetic field (IMF). During such conditions, a By component with the same ...
• #### The Magnitude of IMF By Influences the Magnetotail Response to Solar Wind Forcing ﻿

(Journal article; Peer reviewed, 2021)
The dynamics of substorms are known to be dominated by the North-South (Bz) component of the Interplanetary Magnetic Field (IMF), which is the most important driver of the dayside reconnection. Even though the dawn-dusk ...
• #### Experimental Evidence for an Attractive p-φ Interaction ﻿

(Journal article; Peer reviewed, 2021)
This Letter presents the first experimental evidence of the attractive strong interaction between a proton and a ϕ meson. The result is obtained from two-particle correlations of combined p-ϕ⊕ p¯-ϕ pairs measured in ...

(Journal article; Peer reviewed, 2021)
Measurements of event-by-event fluctuations of charged-particle multiplicities in Pb–Pb collisions at √sNN = 2.76 TeV using the ALICE detector at the CERN Large Hadron Collider (LHC) are presented in the pseudorapidity ...
• #### Λc+ Production and Baryon-to-Meson Ratios in pp and p-Pb Collisions at √sNN=5.02 TeV at the LHC ﻿

(Journal article; Peer reviewed, 2021)
The prompt production of the charm baryon Λ+c and the Λ+c/D0 production ratios were measured at midrapidity with the ALICE detector in pp and p-Pb collisions at √sNN=5.02 TeV. These new measurements show a clear decrease ...
• #### Light neutral meson production in heavy ion collisions with ALICE in the era of precision physics at the LHC ﻿

(Journal article; Peer reviewed, 2021)
The production of light neutral mesons in AA collisions probes the physics of the Quark-Gluon Plasma (QGP), which is formed in heavy-ion collisions at the LHC. More specifically, the centrality dependent neutral meson ...

(Journal article; Peer reviewed, 2021)
Measurement of short-lived hadronic resonances are used to study different aspects of particle production and collision dynamics in pp, p–A and relativistic heavy-ion collisions. The yields of resonances are sensitive to ...
• #### Global Frequency and Geographical Distribution of Nighttime Streamer Corona Discharges (BLUEs) in Thunderclouds ﻿

(Journal article; Peer reviewed, 2021)
Blue LUminous Events (BLUEs) are transient corona discharges occurring in thunderclouds and characterized by strong 337.0 nm light flashes with absent (or weak) 777.4 nm component. We present the first nighttime climatology ...
• #### Challenging aspects of critical thinking : A mixed-methods study of students’ test results, students’ reasoning, and teaching strategies ﻿
