Long-range near-side correlation in $e^+e^-$ Collisions at 183-209 GeV with ALEPH Archived Data
/ Chen, Yu-Chen (MIT) ; Chen, Yi (MIT) ; Badea, Anthony (Chicago U.) ; Baty, Austin (Chicago U.) ; Innocenti, Gian Michele (CERN) ; Maggi, Marcello (INFN, Bari) ; McGinn, Christopher (MIT) ; Peters, Michael (MIT) ; Sheng, Tzu-An (MIT) ; Thaler, Jesse (MIT) et al.
The first measurement of two-particle angular correlations for charged particles with LEP-II data is presented. The study is performed using archived hadronic $e^+e^-$ data collected by ALEPH at center-of-mass energies up to 209 GeV, above the $W^+W^-$ production threshold, which provide access to unprecedented charged-particle multiplicities and more complex color-string configurations if compared to previous measurements at LEP-I energies.

The first measurement of anti-kT jets and two-particle angular correlations
of charged particles emitted in high energy e+e− annihilation is
presented. The archived data at a center-of-mass energy of 91 GeV were
collected with the ALEPH detector at LEP between 1992 and 1994. [...]

Application of Quantum Machine Learning using the Quantum Kernel Algorithm on High Energy Physics Analysis at the LHC

Quantum machine learning could possibly become a valuable alternative to classical machine learning for applications in High Energy Physics by offering computational speed-ups. In this study, we employ a support vector machine with a quantum kernel estimator (QSVM-Kernel method) to a recent LHC flagship physics analysis: $t\bar{t}H$ (Higgs boson production in association with a top quark pair).

/R. C. Group
We present a measurement of the $W$-boson mass, $M_W$, using data corresponding to 2.2/fb of integrated luminosity collected in ppbar collisions at $\sqrt{s}$ = 1.96 TeV with the CDF II detector at the Fermilab Tevatron. The selected sample of 470126 $W\to e\nu$ candidates and 624708 $W\to\mu\nu$ candidates yields the measurement $M_W = 80387\pm 12$ (stat) $\pm 15$ (syst)$ = 80387 \pm 19$ MeV$/c^2$ . [...]
