75. A new Scattering and Neutrino Detector at the LHC (SND@LHC)

Elena Graverini (EPFL - Ecole Polytechnique Federale Lausanne (CH))

SND@LHC is a compact and stand-alone experiment to perform measurements with neutrinos and long lived particles produced at the LHC in a hitherto unexplored pseudo-rapidity region of 7.2 < 𝜂 < 8.6, complementary to all the other experiments at the LHC. The experiment is located 480 m downstream of IP1 in the unused TI18 tunnel. The detector is composed of a hybrid system based on an 800 kg...

85. Consistent Kinetic Mixing

Patrick Foldenauer

Extensions of the Standard Model (SM) with new Abelian gauge groups allow for kinetic mixing between the new gauge bosons and the hypercharge gauge boson, resulting in mixing with the photon. In many models the mixing with the hypercharge gauge boson captures only part of the kinetic mixing term with the photon, since the new gauge bosons can also mix with the neutral component of the...

69. Inelastic Dirac Dark Matter

Sam Junius

Feebly interacting thermal relics are promising dark matter candidates.
We introduce inelastic Dirac Dark Matter, a new model with two Dirac fermions in the MeV-GeV mass range. At feeble couplings, dark matter can depart from chemical as well as kinetic equilibrium with the Standard Model during the early stages of its evolution so that its relic abundance is not necessarily set by the well...

70. Jupiter missions as in situ probes of long-lived dark mediators

LINGFENG LI (Brown U.)

Jupiter, the fascinating largest planet in the solar system, has been visited by nine spacecraft with the latest one being the Juno orbiter, which is still circling around it. These Jupiter missions have collected a significant amount of data about Jovian properties. In this paper, we show that one type of the in situ measurements on the relativistic electron fluxes could be used to probe dark...

63. Large Energy Singles as a Probe of Dark Matter

Basudeb Dasgupta (TIFR Mumbai)

Large liquid scintillator detectors, such as JUNO, present new opportunities. We show that “Large Energy Singles”, i.e., events with visible scintillation energy greater than 15 MeV but no other associated tags, can competitively probe a variety of new physics scenarios, such as boosted dark matter and annihilation of galactic dark matter to sterile neutrinos, in addition to detailed studies...

19. Light Dark Matter in the MeV-GeV range: overview of direct detection searches

98. Lyman-α constraints on freeze-in and superWIMPs

Quentin Decant (ULB)

Dark matter (DM) from freeze-in or superWIMP production is well known to imprint non-cold DM signatures on cosmological observables. We derive constraints from Lyman-α forest
observations for both cases, basing ourselves on a reinterpretation of the existing Lyman-α limits
on thermal warm DM. We exclude DM masses below 15 keV for freeze-in, in good agreement
with previous literature, and...
