The ETROC1: The first full chain precision timing prototype for CMS MTD Endcap Timing Layer (ETL) upgrade / Liu, Tiehui Ted (speaker) (Fermi National Accelerator Lab. (US))
The Endcap Timing Readout Chip (ETROC) is being developed for the CMS MTD Endcap Timing Layer (ETL) for the HL-LHC, to process LGAD signals with time resolution down to 30ps per track. The ETROC1 is the first full chain precision timing prototype, including preamplifier and discriminator, as well as a new low power TDC design that performs time-of-arrival (TOA) and time-over-threshold (TOT) measurements.

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. [...]

A High-performance Track Fitter for Use in Ultra-fast Electronics / Clement, Emyr John (Bristol U.) ; De Mattia, Marco (Texas A-M) ; Dutta, Suchandra (Saha Inst.) ; Eusebi, Ricardo (Texas A-M) ; Fu, Yu (Florida U.) ; Hahn, Kristan Allan (Northwestern U.) ; Hu, Zhen (Fermilab) ; Jindariani, Sergo (Fermilab) ; Konigsberg, Jacobo (Florida U.) ; Liu, Tiehui Ted (Fermilab) et al.
This article describes a new charged-particle track fitting algorithm designed for use in high-speed electronics applications such as hardware-based triggers in high-energy physics experiments. Following a novel technique designed for fast electronics, the positions of the hits on the detector are transformed before being passed to a linearized track parameter fit. [...]

A Study of the Energy Dependence of the Underlying Event in Proton-Antiproton Collisions / for the CDF Collaboration
We study charged particle production in proton-antiproton collisions at 300 GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of eta-phi space; toward, away, and transverse. [...]

ATCA-based ATLAS FTK input interface system / on behalf of the ATLAS Collaboration
The first stage of the ATLAS Fast TracKer (FTK) is an ATCA-based input interface system, where hits from the entire silicon tracker are clustered and organized into overlapping eta-phi trigger towers before being sent to the tracking engines. [...]

Prototype performance studies of a Full Mesh ATCA-based General Purpose Data Processing Board / Okumura, Yasuyuki (Chicago U. ; Fermilab) ; Olsen, Jamieson (Fermilab) ; Liu, Tiehui Ted (Fermilab) ; Yin, Hang (Fermilab)
High luminosity conditions at the LHC pose many unique challenges for potential silicon based track trigger systems. One of the major challenges is data formatting, where hits from thousands of silicon modules must first be shared and organized into overlapping eta-phi trigger towers. [...]

A precise measurement of the $W$-boson mass with the Collider Detector at Fermilab / Aaltonen, Timo Antero (Helsinki U. ; Helsinki Inst. of Phys.) ; Amerio, Silvia (INFN, Padua ; Padua U.) ; Amidei, Dante E (Michigan U.) ; Anastassov, Anton Iankov (Fermilab ; Northwestern U.) ; Annovi, Alberto (Frascati) ; Antos, Jaroslav (Comenius U. ; Kosice, IEF) ; Apollinari, Giorgio (Fermilab) ; Appel, Jeffrey A (Fermilab) ; Arisawa, Tetsuo (Waseda U.) ; Artikov, Akram Muzafarovich (Dubna, JINR) et al. /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$/c^2$ . [...]

Study of orbitally excited $B$ mesons and evidence for a new $B\pi$ resonance / Aaltonen, Timo Antero (Helsinki U. ; Helsinki Inst. of Phys.) ; Amerio, Silvia (INFN, Padua ; Padua U.) ; Amidei, Dante E (Michigan U.) ; Anastassov, Anton Iankov (Fermilab ; Northwestern U.) ; Annovi, Alberto (Frascati) ; Antos, Jaroslav (Comenius U. ; Kosice, IEF) ; Apollinari, Giorgio (Fermilab) ; Appel, Jeffrey A (Fermilab) ; Arisawa, Tetsuo (Waseda U.) ; Artikov, Akram Muzafarovich (Dubna, JINR) et al. /R. C. Group
Using the full CDF Run II data sample, we report evidence for a new resonance, which we refer to as B(5970), found simultaneously in the $B^0\pi^+$ and $B^+\pi^-$ mass distributions with a significance of 4.4 standard deviations. We further report the first study of resonances consistent with orbitally excited $B^{+}$ mesons and an updated measurement of the properties of orbitally excited $B^0$ and $B_s^0$ mesons. [...]
