SUMMARY:SPEAKER: Noah Sailer (UC Berkeley)- Title: Accurate cosmology from CMB lensing and galaxy surveys
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate:  April 7\, 2023 \nTime: 12:00- 1:00 pm \nLocation:  Sessler Conference Room- 50A-5132 \n\nSpeaker: Noah Sailer (UC Berkeley) \nTitle: Accurate cosmology from CMB lensing and galaxy surveys \nAbstract: \nJoint analyses of CMB lensing and spectroscopically-calibrated galaxies have the ability to measure the evolution of matter fluctuations out to high redshifts without the complications of photometric redshift uncertainties and intrinsic alignments. These measurements are rapidly becoming one of the more powerful tools in a cosmologist’s toolkit\, enabling precise (and accurate) inference of cosmological parameters and potential deviations from ΛCDM. While cross-correlations are typically more robust against systematic effects\, correlated systematics arising from (extra)galactic foreground contamination and masking induce significant biases if not properly accounted for. I will discuss progress towards mitigating these effects\, the implementation of these methods in an ongoing cross-correlation analysis of DESI luminous red galaxies and CMB lensing from ACT\, and the prospects of future analyses with Stage-V spectroscopy and CMB-S4. \n  \nJoin Zoom Meeting\nhttps://lbnl.zoom.uspwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\n\nPasscode: 247722

SUMMARY:Speaker: Gabriela Rodrigues Araujo (University of Zurich)- Title: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals
DESCRIPTION:SPECIAL INPA SEMINAR \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 10\, 2023 \nTIME: 4:00  pm \nTITLE: Light-sheet microscopy of color centers: A new venue for neutrino and dark matter detection with passive crystals \nABSTRACT: Most of the techniques currently used to detect nuclear recoils from dark matter and neutrinos rely on the collection of charge\, prompt scintillation photons or phonons. In this talk\, I will discuss a new approach: The use of light-sheet fluorescence microscopy to detect a specific type of crystal defect\, so called color centers (CCs)\, which could be induced by nuclear recoils in solid-state materials. Since CCs require little energy to form (10-50 eV)\, the proposed detectors can search for particle interactions at unexplored low-energy regions. Despite the nm-size of these defects\, excited CCs re-emit color in the visible range\, a feature that facilitates their detection. To make this detection channel competitive for rare-event search\, a fast imaging method of single CCs is necessary. The PALEOCCENE collaboration works towards this goal: a scalable read-out of CCs for passive detectors of neutrinos and dark matter. In the talk I will discuss the concept\, the current R&D and possible applications for dark matter\, CEvNS\, and nuclear-nonproliferation safeguards. \nZOOM INFORMATION – \nZoom Meeting\nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\n\nPasscode: 247722 \n

SUMMARY:SPEAKER: Lisa Schlueter (TU Munich)-TITLE: Neutrino-Mass Analysis with sub-eV Sensitivity and Search for Light Sterile Neutrinos with the KATRIN Experiment
DESCRIPTION:SPECIAL INPA SEMINAR \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 11\, 2023 \nTIME: 12:00  pm \nTITLE: Neutrino-Mass Analysis with sub-eV Sensitivity and Search for Light Sterile Neutrinos with the KATRIN Experiment \nABSTRACT: The KArlsruhe TRItium Neutrino (KATRIN) experiment is designed to determine the effective mass of the electron-antineutrino with a target sensitivity of 200 meV/c2 (90% C.L.) in a direct and model-independent way. KATRIN uses a strong gaseous windowless Tritium source associated with a large high-resolution spectrometer (MAC-E filter) to analyze precisely the electron energies from the source. The neutrino mass can be inferred from the shape of the tritium β-decay spectrum in the endpoint region. After global commissioning of the apparatus with Tritium in 2018\, KATRIN started its first neutrino mass measurement campaign in spring 2019. This talk presents the data and the analysis of the first two measurement campaigns. In terms of effective electron antineutrino mass\, an upper limit of 0.8 eV (90% C.L.) could be inferred\, reaching for the first time into the sub-eV regime. Moreover\, to exploit the full physics potential of the KATRIN experiment\, a search for light sterile neutrinos was conducted. As no sterile-neutrino signal is observed\, exclusion contours are drawn at 95% C.L. covering the parameter space of the long-persisting light-sterile neutrino anomalies to a great extent. \nZOOM INFORMATION – \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:SPEAKER: Prof. Christian Weinheimer (University of Münster)-TITLE: The dark matter experiment XENONnT and first WIMP results
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 14\, 2023 \nTIME: 12:00- 1:00 PM \nTITLE: The dark matter experiment XENONnT and first WIMP results \nABSTRACT: Evidence for about 6 times more matter in the universe than normal\nmatter is coming from cosmological observations and analyses on all\nscales. What this exotic dark matter is remains still a secret.\nThe direct search experiment for dark matter XENONnT located at the\nItalian underground laboratory LNGS is looking for weakly interacting\nmassive particles (WIMPs) and other rare event physics. As an upgrade of\nthe previous experiment XENON1T it uses a dual-phase time projection\nchamber with a total mass of 8.5t of liquid xenon. The recent electron\nrecoil data from a 1.16 t*yr exposure of XENONnT allowed to set\nstringent limits on solar axions\, an enhanced neutrino magnetic moment\nand bosonic dark matter. XENONnT’s unprecedented low background\noriginates from very careful material selecting and screening as well as\nfrom active removal of Kr-85 and Rn-222 by cryogenic distillation. This\nlow background rate allows for a rich physics search program with\nXENONnT with WIMPs being the main objective.\nIn this talk the status of the XENONnt experiment and its first WIMP\nsearch results from a blind analysis in an energy range between 3.1 keV\nand 60.0 keV and an exposure of approximately 1.1 tonne-year is presented.” \nJoin Zoom  \nhttps://lbnl.zoom.us/j/95016696011?pwd=Tk1XOW1Xd3RYRnlsc2tEYmRWZlVVZz09 \nMeeting ID: 950 1669 6011\nPasscode: 247722
