DESCRIPTION:Speakers: Silvia Lucia Correa Angel (Federal University of Rio
  Grande do Norte -UFRN\, International Institute of Physics - IIP)\nThe da
 rk photon is a new gauge boson that naturally arises in many beyond the St
 andard Model theoretical models\, featuring\ninteractions that resemble qu
 antum electrodynamics. Due to this feature\, it is often considered the po
 rtal between dark and visible\nsectors. For this reason\, it has become th
 e target of many experimental searches worldwide. In this work\, we propos
 e a search for dark\nphotons based on the Inverse Compton scattering\, $\\
 gamma e^- \\rightarrow A^\\prime e^-$\, to be conducted at the Brazilian\n
 Synchrotron Light Laboratory (LNLS). In this setup\, photons from a laser 
 source would impinge on the accelerated electron beam\npresent at the LNLS
 \, producing a dark photon in the final state. Taking advantage of the pho
 ton counting technique\, we derive the\nprojected sensitivity of this prop
 osed dark sector detector by considering the energy of the incident photon
  about 1 eV and an electron\nbeam of 3 GeV. We show that this experimental
  setup could pave the way to the first Latin-American Dark Sector detector
  capable of\ncovering an unexplored region of parameter space and confirmi
 ng results from previous searches via astrophysical sources\, thus\nconsti
 tuting a promising probe for dark sectors in the future.\n\nhttps://indico

DESCRIPTION:Speakers: Rafael Lopez Noe (IFT UAM-CSIC)\nIn this work\, we a
 pply recent direct detection constraints on electron recoils to freeze-in 
 Dark Matter (DM) models. Due to recent results obtained by direct detectio
 n experiments\, especially DAMIC-M\, the dark photon scenario is severely 
 constrained. However\, there are different scenarios in which these bounds
  can be avoided. In freeze-in models\, the scaling of the DM relic abundan
 ce allows the dark photon to be a subdominant component. DAMIC-M results r
 ules out up to 50 %\, with future experiments aiming to constraint up to 0
 .001 %. Next\, we show that in scenarios where the main DM production chan
 nels are not electron-positron or plasmon decay\, such as Lμ − Lτ \, t
 he main contributions comes from ν\, that are now charged to the Z′. Th
 us\, such models avoid the current direct detection constraints on electro
 n recoils.\nAs a result\, we provide new targets for upcoming direct detec
 tion experiments looking for electron recoils such as DAMIC\, SuperCDMS or
  Oscura.\n\nhttps://indico.ift.uam-csic.es/event/29/contributions/496/

DESCRIPTION:Speakers: Alejandro Muñoz Ovalle (IFIC (CSIC/UV))\nApart from
  its gravitational interactions\, dark matter (DM) has remained so\nfar el
 usive in laboratory searches. One possible explanation is that the relevan
 t interactions\nto explain its relic abundance are mainly gravitational. I
 n this work we consider an extra-\ndimensional Randall-Sundrum scenario wi
 th a TeV-PeV IR brane\, where the Standard\nModel is located\, and a GeV-T
 eV deep IR (DIR) one\, where the DM lies. When the\ncurvatures of the bulk
  to the left and right of the IR brane are very similar\, the tension\nof 
 the IR brane is significantly smaller than that of the other two branes\, 
 and therefore\nwe term it “evanescent”. In this setup\, the relic abun
 dance of DM arises from the freeze-\nout mechanism\, thanks to DM annihila
 tions into radions and gravitons. Focusing on a\nscalar singlet DM candida
 te\, we compute and apply current and future constraints from\ndirect\, in
 direct and collider-based searches. Our findings demonstrate the viability
  of this\nscenario and highlight its potential testability in upcoming exp
 eriments. We also discuss\nthe possibility of inferring the number of bran
 es if the radion and several Kaluza-Klein\ngraviton resonances are detecte
 d at a future collider.\n\nhttps://indico.ift.uam-csic.es/event/29/contrib

DESCRIPTION:Speakers: Baibhab Pattnaik (Instituto de Física Corpuscular (
 Universidad de Valencia-CSIC))\nWe demonstrate the possibility of testing 
 Heavy Neutral Leptons (HNLs) using "cosmic ray beam-dumps'' : setups where
  high-energy incident cosmic rays impinge on the Earth's atmosphere and th
 en on the Earth's surface. We focus on HNL production from atmospherically
  produced parent meson decays\, and examine them as a possible explanation
  of the appearing Cherenkov showers observed by the SHALON Cherenkov teles
 cope and the ultra-high energy events detected by the ANITA neutrino exper
 iment. Further\, we propose two new experimental setups with improved sens
 itivities\, namely a Cherenkov telescope pointing at a sub-horizontal angl
 e and shielded by the mountain cliff at Mt. Thor\, and SPYGLASS: a geostat
 ionary satellite that observes part of the Sahara desert. Our results show
  that that the Mt. Thor experiment can probe currently untested HNL parame
 ter space below the kaon mass\; while SPYGLASS can significantly increase 
 the HNL parameter space coverage in the mass range from 10 MeV up to 2 GeV
  and test neutrino mixing $|U_{\\alpha4}|^2$ down to $10^{-11}$ for masses
  around 300 MeV.\n\nhttps://indico.ift.uam-csic.es/event/29/contributions/

DESCRIPTION:Speakers: Jacopo Nava (U. Bologna)\nNeutrinos from blazars can
  originate from inelastic scatterings between the protons within their jet
 s and sub-GeV dark matter (DM) around them. I will show how this mechanism
  can potentially account for both the IceCube detections of neutrinos from
  the blazar TXS 0506+056\, that are\notherwise challenging for astrophysic
 al models of its jet\, and also saturate the measured diffuse astrophysica
 l neutrino flux at high energies\nThe same DM-proton interactions will als
 o induce an upscattered DM flux\, which could yield measurable nuclear rec
 oil signals at neutrino detectors\, such as Super-K\, JUNO and DUNE. I wil
 l show that searches for such DM component leave room for a variety of DM 
 models to explain observations of IceCube high-energy neutrinos\, and will
  provide future tests of this hypothesis.\n\nhttps://indico.ift.uam-csic.e

DESCRIPTION:Speakers: Pablo Blanco (IFT UAM/CSIC)\nThe recent observations
  of solar $\\rm ^8B$ neutrinos via coherent elastic neutrino–nucleus sca
 ttering (CEνNS) by the PANDAX-4T and XENONnT collaborations mark the firs
 t detection of the so-called “neutrino fog” — an irreducible backgro
 und for future direct dark matter searches. In this talk\, I will show how
  these results enable powerful new probes of light mediators coupling to n
 eutrinos and quarks. Using the new available datasets from PANDAX-4T and X
 ENONnT\, we derive leading constraints on sub-GeV scalar and vector mediat
 ors\, including scenarios with flavor-universal or mass-proportional quark
  couplings. \n\nI will also discuss the impact of subdominant neutrino int
 eraction channels — such as neutrino–electron scattering and the Migda
 l effect — and demonstrate that\, while typically neglected\, they can c
 ontribute non-negligibly in S2-only analyses. These results highlight the 
 potential of next-generation liquid xenon detectors not only for dark matt
 er discovery\, but also as sensitive laboratories for light new physics in
  the neutrino sector.\n\nhttps://indico.ift.uam-csic.es/event/29/contribut

 they can decay into \ninfrared\, optical and ultraviolet photons \n{with a
  decay lifetime larger than the age of the Universe}. \nWe analyze multi-w

DESCRIPTION:Speakers: David Alonso-González (IFT (UAM-CSIC))\nIn this tal
 k I will present a new potential signature of supernovae axion-like partic
 les (ALPs)  in neutrino water Cherenkov detectors. If ALPs couple to proto
 ns\, then they can be detected through ALP absorption on free protons\, $a
 \\ p→p\\ γ$\, where the resulting photon has approximately the energy o
 f the ALP. This new signature is complementary to the usual one from oxyge
 n de-excitation\, and can be exploited in various ways.\n\nI will first ar
 gue that ALPs with MeV masses can be produced with semi-relativistic veloc
 ities in core-collapse galactic supernovae and that they can constitute a 
 diffuse flux formed by the overlap of the ALP fluxes. Using Super-Kamiokan
 de data\, new constraints on the ALP-proton coupling can be derived in reg
 ions that cooling bounds cannot probe. For lighter ALPs\, the conditions f
 or a diffuse flux fail. Nevertheless\, they can still be looked for on ind
 ividual (future) neighbouring supernovae. I will show that this new signat
 ure\, combined with the one expected from oxygen de-excitation\, would all
 ow us to disentangle ALP-neutron and ALP-proton couplings.\n\nhttps://indi
