While the QCD axion is often considered to be necessarily light ($\lesssim$ eV), recent work has opened a viable and interesting parameter space for heavy axions, which solve both the
Search for the rare decay of the W boson into a pion and a photon in proton-proton collisions at $\sqrt{s} = $ 13 TeV. (arXiv:2011.06028v1 [hep-ex])
A search is performed for the rare decay W$^\pm\to\pi^\pm\gamma$ in proton-proton collisions at $\sqrt{s} =$ 13 TeV. Data corresponding to an integrated luminosity of 137 fb$^{-1}$ were collected during 2016
$\rm \Lambda_{c}^{+}$ production and baryon-to-meson ratios in pp and p-Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV at the LHC. (arXiv:2011.06078v1 [nucl-ex])
The prompt production of the charmed baryon $\rm \Lambda_{c}^{+}$ and the $\rm \Lambda_{c}^{+}/\mathrm {D^0}$ production ratios were measured at midrapidity with the ALICE detector in pp and p-Pb collisions at
$\mathrm{\Lambda_{c}^{+}}$ production in pp and in p-Pb collisions at $\sqrt{s_{\rm {NN}}} = 5.02$ TeV. (arXiv:2011.06079v1 [nucl-ex])
The production cross section of prompt $\mathrm{\Lambda_{c}^{+}}$ charmed baryons was measured with the ALICE detector at the LHC at midrapidity in proton-proton (pp) and proton-lead (p-Pb) collisions at a centre-of-mass
Making the Universe at 20 MeV. (arXiv:2011.06115v1 [hep-ph])
We present a testable mechanism of low-scale baryogenesis and dark matter production in which neither baryon nor lepton number are violated. Charged $D$ mesons are produced out-of-equilibrium at tens of
Calibration Strategy of the JUNO Experiment. (arXiv:2011.06405v1 [physics.ins-det])
We present the calibration strategy for the 20 kton liquid scintillator central detector of the Jiangmen Underground Neutrino Observatory (JUNO). By utilizing a comprehensive multiple-source and multiple-positional calibration program, in
Ground Level Muon Flux Variation in a Cosmic Rays Simulation. (arXiv:2011.06480v1 [hep-ph])
The oscillatory movements of atmospheric air masses has been claimed to be the origin of the muon flux variation measured at the ground level. Using a cosmic ray toolkit (CORSIKA),
Topping-up multilepton plus b-jets anomalies at the LHC with a $Z’$ boson. (arXiv:2011.06514v1 [hep-ph])
During the last years ATLAS and CMS have reported a number of slight to mild discrepancies in signatures of multileptons plus $b$-jets in analyses such as $t\bar t H$, $t\bar
UPconversion Loop Oscillator Axion Detection experiment: A precision frequency interferometric axion dark matter search with a Cylindrical Microwave Cavity. (arXiv:1912.07751v3 [hep-ex] UPDATED)
First experimental results from a room-temperature table-top phase-sensitive axion haloscope experiment are presented. The technique exploits the axion-photon coupling between two photonic resonator-oscillators excited in a single cavity, allowing low-mass
X17: A new force, or evidence for a hard $\gamma +\gamma$ process?. (arXiv:2003.05722v5 [hep-ph] UPDATED)
It is investigated whether the “X17 puzzle” might be explained by a nuclear decay chain and a conversion of the two resulting highly energetic $\gamma$s into an electron-positron pair. It
