(Wayne State U.) et al.
This work shows how it is possible to reconstruct SuperKEKB's beam parameters using a Neural Network with beamstrahlung signal from the Large Angle Beamstrahlung Monitor (LABM) as input. We describe the device, the model, and discuss the results..

Charge-dependent anisotropic flow studies and the search for the Chiral Magnetic Wave in ALICE / Belmont, R. (Wayne State U.) /for the ALICE Collaboration
Theoretical calculations have shown the possibility of P-violating bubbles in the QCD vacuum, which in combination with the strong magnetic field created in off-central heavy-ion collisions lead to novel effects such as the Chiral Magnetic Effect (CME) and the Chiral Separation Effect (CSE). A coupling between the CME and the CSE produces a wave-like excitation called the Chiral Magnetic Wave (CMW). [...]

Characterizing system dynamics with two-particle transverse momentum correlations in pp collisions at $\sqrt{s} = 7\;\text{TeV}$ and p–Pb collisions at $\sqrt{s_{NN}} = 5.02\;\text{TeV}$ / Gonzalez, Victor (Wayne State U.) /ALICE Collaboration
The two-particle differential transverse momentum correlator $G_{2}$ recently measured in Pb$-$Pb collisions, emerged as a powerful tool to gain insight into particle production mechanisms and to infer transport properties such as the ratio of shear viscosity to entropy density of the medium created in Pb$-$Pb collisions. In this poster, recent ALICE measurements of this correlator in pp collisions at $\sqrt{s}=7$ and p$-$Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV are presented to search, in particular, for viscous effects expected to arise in fluid-like systems produced in these collisions.

Measurement of the charge asymmetry of electrons from the decays of $W$ bosons produced in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV / CDF Collaboration
At the Fermilab Tevatron proton-antiproton ($p\bar{p}$) collider, high-mass electron-neutrino ($e\nu$) pairs are produced predominantly in the process $p \bar{p} \rightarrow W(\rightarrow e\nu) + X$. The asymmetry of the electron and positron yield as a function of their pseudorapidity constrain the slope of the ratio of the $u$- to $d$-quark parton distributions versus the fraction of the proton momentum carried by the quarks.

Closing the Wedge: Search Strategies for Extended Higgs Sectors with Heavy Flavor Final States / Gori, Stefania (Perimeter Inst. Theor. Phys. ; Cincinnati U.) ; Kim, Ian-Woo (CERN ; UC, San Francisco) ; Shah, Nausheen R. (Wayne State U.) ; Zurek, Kathryn M. (LBNL, Berkeley ; UC, Berkeley)
We consider search strategies for an extended Higgs sector at the high-luminosity LHC14 utilizing multi-top final states. In the framework of a Two Higgs Doublet Model, the purely top final states ($t\bar t, \, 4t$) are important channels for heavy Higgs bosons with masses in the wedge above $2\,m_t$ and at low values of $\tan\beta$, while a $2 b 2t$ final state is most relevant at moderate values of $\tan \beta$.
