The U.S. CMS HL-LHC R&D Strategic Plan

Oliver Gutsche, Tulika Bose, Margaret Votava +13

The HL-LHC run is anticipated to start at the end of this decade and will pose a significant challenge for the scale of the HEP software and computing infrastructure. The mission o…

DarkQuest: A dark sector upgrade to SpinQuest at the 120 GeV Fermilab Main Injector

Aram Apyan, Brian Batell, Asher Berlin +36

Expanding the mass range and techniques by which we search for dark matter is an important part of the worldwide particle physics program. Accelerator-based searches for dark matte…

LHC Dark Matter Working Group: Next-generation spin-0 dark matter models

Tomohiro Abe, Yoav Afik, Andreas Albert +50

Dark matter (DM) simplified models are by now commonly used by the ATLAS and CMS Collaborations to interpret searches for missing transverse energy ( $E_{T}^{miss}$ ). The coher…

Measurement of the Decay Asymmetry Parameters in $Λ_{c}^{+} \to Λ π^{+}$ and $Λ_{c}^{+} \to Σ^{+} π^{0}$

M. Bishai

We have measured the weak decay asymmetry parameters ($\aLC $) for two \LC\ decay modes. Our measurements are $\aLC = -0.94^{+0.21+0.12}_{-0.06-0.06} $ for the decay mode $Λ_c^+ \t…

Measurement of the branching fraction for $Υ (1 S) \to τ^{+} τ^{-}$

D. Cinabro

We have studied the leptonic decay of the $Υ (1 S)$ resonance into tau pairs using the CLEO II detector. A clean sample of tau pair events is identified via events containing two cha…

Measurement of the B -> D^* l nu Branching Fractions and |Vcb|

The CLEO Collaboration

We study the exclusive semileptonic B meson decays B- -> D*0 l- nu and B0 -> D*+ l- nu using data collected with the CLEO II detector at CESR. We present measurements of the branch…

Production and Decay of D_1(2420)^0 and D_2^*(2460)^0

The CLEO Collaboration

We have investigated $D^{+} π^{-}$ and $D^{*+} π^{-}$ final states and observed the two established $L = 1$ charmed mesons, the $D_{1} (2420)^{0}$ with mass $242 1_{- 2 - 2}^{+ 1 + 2}$ MeV/c $^{2}$ …

A Measurement of $B (D_{s} \to ϕ l^{+} ν) / c a l B (D_{s} \to ϕ π^{+})$

The CLEO Collaboration

Using the CLEO~II detector at CESR, we have measured the ratio of branching fractions $B (D_{s}^{+} \to ϕ e^{+} ν) / B (D_{s}^{+} \to ϕ π^{+}) = 0.54 \pm 0.05 \pm 0.04$ . We use this meas…

Study of the Decay $Λ_c \to Λl^+ ν_{l}

The CLEO Collaboration

Using the CLEO II detector at CESR, we observe 500 $Λ l^{+}$ pairs consistent with the semileptonic decay $Λ_{c} \to Λ l^{+} ν_{l}$ . We measure $σ(e^+ e^- \to Λ_c X) \dot {cal B}(Λ_c^+ \to…
