Hyperons during proto-neutron star deleptonization and the emission of dark flavoured particles
/ Fischer, Tobias (Wroclaw U.) ; Martin Camalich, Jorge (IAC, La Laguna ; Laguna U., Tenerife ; CERN) ; Kochankovski, Hristijan (ICC, Barcelona U. ; Skopje U.) ; Tolos, Laura (Barcelona, IEEC ; Frankfurt U., FIAS ; Bucharest, Inst. Space Science)
Complementary to high-energy experimental efforts, indirect astrophysical searches of particles beyond the standard model have long been pursued. The present article follows the latter approach and considers, for the first time, the self-consistent treatment of the energy losses from dark flavoured particles produced in the decay of hyperons during a core-collapse supernova (CCSN). [...]

Supernova limits on muonic dark forces
/ Manzari, Claudio Andrea (UC, Berkeley ; LBL, Berkeley) ; Martin Camalich, Jorge (IAC, La Laguna ; Laguna U., Tenerife ; CERN) ; Spinner, Jonas (U. Heidelberg, ITP ; KIT, Karlsruhe, TTP) ; Ziegler, Robert (Freiburg U. ; KIT, Karlsruhe, TTP)
Proto-neutron stars formed during core-collapse supernovae are hot and dense environments that contain a sizable population of muons. If these interact with new long-lived particles with masses up to roughly 100 MeV, the latter can be produced and escape from the stellar plasma, causing an excessive energy loss constrained by observations of SN 1987A. [...]

New Physics Searches at Kaon and Hyperon Factories

(Los Alamos) ; Bansal, Saurabh (Cincinnati U.) ; Bauer, Martin (Durham U., ICC) ; Brod, Joachim (Cincinnati U.) ; Chobanova, Veronika (Santiago de Compostela U., IGFAE) et al.
Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. [...]

Quark Flavor Phenomenology of the QCD Axion
/ Martin Camalich, Jorge (IAC, La Laguna ; Laguna U., Tenerife) ; Pospelov, Maxim (Minnesota U. ; Minnesota U., Theor. Phys. Inst.) ; Vuong, Pham Ngoc Hoa (LPSC, Grenoble) ; Ziegler, Robert (CERN ; KIT, Karlsruhe, TTP) ; Zupan, Jure (Cincinnati U.)
Axion models with generation-dependent Peccei-Quinn charges can lead to flavor-changing neutral currents, thus motivating QCD axion searches at precision flavor experiments. We rigorously derive limits on the most general effective flavor-violating couplings from current measurements and assess their discovery potential. [...]

Report from Working Group 3 : Beyond the Standard Model physics at the HL-LHC and HE-LHC
/ Cid Vidal, Xabier (Santiago de Compostela U., IGFAE) ; D'Onofrio, Monica (Liverpool U.) ; Fox, Patrick J (Fermilab) ; Torre, Riccardo (CERN ; INFN, Genoa) ; Ulmer, Keith A (Colorado U.) ; Aboubrahim, Amin (Northeastern U.) ; Albert, Andreas (RWTH Aachen U.) ; Alimena, Juliette (Ohio State U., Columbus (main)) ; Allanach, Benjamin C (Cambridge U., DAMTP) ; Alpigiani, Cristiano (Washington U., Seattle) et al.
This is the third out of five chapters of the final report [1] of the Workshop on Physics at HL-LHC, and perspectives on HE-LHC [2]. It is devoted to the study of the potential, in the search for Beyond the Standard Model (BSM) physics, of the High Luminosity (HL) phase of the LHC, defined as $3$ ab$^{-1}$ of data taken at a centre-of-mass energy of 14 TeV, and of a possible future upgrade, the High Energy (HE) LHC, defined as $15$ ab$^{-1}$ of data at a centre-of-mass energy of 27 TeV.

The Mono-Tau Menace: From $B$ Decays to High-$p_T$ Tails
/ Greljo, Admir (CERN) ; Martin Camalich, Jorge (CERN ; IAC, La Laguna ; Laguna U., Tenerife) ; Ruiz-Álvarez, José David (Antioquia U.)
We investigate the crossing-symmetry relation between $b\to c\tau^-\bar\nu$ decay and $b\bar c\to \tau^-\bar\nu$ scattering to derive direct correlations of New Physics in semi-tauonic $B$-meson decays and the mono-tau signature at the LHC ($pp\to\tau_h X$ + MET). Using an exhaustive set of effective operators and heavy mediators we find that the current ATLAS and CMS data constrain scenarios addressing anomalies in $B$-decays. [...]

A clockwork solution to the flavor puzzle
/ Alonso, Rodrigo (CERN) ; Carmona, Adrian (Mainz U., Inst. Phys. ; U. Mainz, PRISMA) ; Dillon, Barry M. (Plymouth U.) ; Kamenik, Jernej F. (Stefan Inst., Ljubljana ; Ljubljana U.) ; Martin Camalich, Jorge (CERN ; IAC, La Laguna) ; Zupan, Jure (Cincinnati U.)
We introduce a set of clockwork models of flavor that can naturally explain the large hierarchies of the Standard Model quark masses and mixing angles. Since the clockwork only contains chains of new vector-like fermions without any other dynamical fields, the flavor constraints allow for relatively light new physics scale. [...]
