/ Andrea, Jeremy (Strasbourg, IPHC) ; Assiouras, Panagiotis (Democritos Nucl. Res. Ctr.) ; Auzinger, Georg (CERN) ; Bhattacharya, Rajarshi (Saha Inst.) ; Canepa, Anadi (Fermilab) ; Chanon, Nicolas Pierre (Lyon, IPN) ; Cherepanov, Vladimir (Florida U.) ; Deelen, Nikkie (UC, San Diego) ; Delcourt, Martin (Louvain U.) ; Dierlamm, Alexander Hermann (KIT, Karlsruhe, EKP) et al.
A new CMS tracker detector will be installed for operation at the High Luminosity LHC\,(HL-LHC). This detector
comprises modules with two closely spaced parallel sensor plates and front-end ASICs capable of transmitting tracking information to the CMS Level-1\,(L1) trigger at the 40\,MHz beam crossing rate. [...]

/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

/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. [...]

Exclusion of exotic top-like quarks with -4/3 electric charge using jet-charge tagging in single-lepton ttbar events at CDF

/R. C. Group
We report on a measurement of the top-quark electric charge in ttbar events in which one W boson originating from the top-quark pair decays into leptons and the other into hadrons. The event sample was collected by the CDF II detector in sqrt(s)=1.96 TeV proton-antiproton collisions and corresponds to 5.6 fb^(-1). [...]

Measurement of the Mass Difference Between Top and Anti-top Quarks at CDF

/R. C. Group
We present a measurement of the mass difference between top ($t$) and anti-top ($\bar{t}$) quarks using $t\bar{t}$ candidate events reconstructed in the final state with one lepton and multiple jets. We use the full data set of Tevatron $\sqrt{s} = 1.96$ TeV proton-antiproton collisions recorded by the CDF II detector, corresponding to an integrated luminosity of 8.7 fb$^{-1}$. [...]

Search for new phenomena in events with two $Z$ bosons and missing transverse momentum in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV

/R. C. Group
We present a search for new phenomena in events with two reconstructed $Z$ bosons and large missing transverse momentum, sensitive to processes $p\bar{p}\rightarrow X_2X_2 \rightarrow Z Z X_1 X_1$, where $X_2$ is an unstable particle decaying as $X_2\rightarrow ZX_1$ and $X_1$ is undetected. The particles $X_1$ and $X_2$ may be, among other possibilities, fourth generation neutrinos or supersymmetric particles. [...]

Flavor Physics in the Quark Sector
/ Antonelli, Mario (Frascati) ; Asner, David Mark (Carleton U.) ; Bauer, D. (Imperial Coll., London) ; Becher, Thomas G. (Fermilab) ; Beneke, M. (Aachen, Tech. Hochsch.) ; Bevan, Adrian John (Queen Mary, U. of London) ; Blanke, Monika (Munich, Max Planck Inst. ; Munich, Tech. U.) ; Bloise, C. (Frascati) ; Bona, Marcella (CERN) ; Bondar, Alexander E. (Novosibirsk, IYF) et al.
One of the major challenges of particle physics has been to gain an in-depth understanding of the role of quark flavor and measurements and theoretical interpretations of their results have advanced tremendously: apart from masses and quantum numbers of flavor particles, there now exist detailed measurements of the characteristics of their interactions allowing stringent tests of Standard Model predictions. Among the most interesting phenomena of flavor physics is the violation of the CP symmetry that has been subtle and difficult to explore. [...]
