Gauged $L^{}_{\mu}{-}L^{}_{\tau}$ at a muon collider / Huang, Guo-yuan (Heidelberg, Max Planck Inst.) ; Queiroz, Farinaldo S (Rio Grande do Norte U.) ; Rodejohann, Werner (Heidelberg, Max Planck Inst.)
We investigate the sensitivity of the projected TeV muon collider to the gauged $L^{}_{\mu}$-$L^{}_{\tau}$ model. Two processes are considered: $Z'$-mediated two-body scatterings $\mu^+ \mu^- \to \ell^+ \ell^-$ with $\ell = \mu$ or $\tau$, and scattering with initial state photon emission, $\mu^+ \mu^- \to \gamma Z',~Z' \to \ell \overline{\ell}$, where $\ell$ can be $\mu$, $\tau$ or $\nu_{\mu/\tau}$. [...]

Probing the RK(*) anomaly at a muon collider / Huang, Guo-yuan (Heidelberg, Max Planck Inst.) ; Jana, Sudip (Heidelberg, Max Planck Inst.) ; Queiroz, Farinaldo S (IIP, Brazil ; Rio Grande do Norte U.) ; Rodejohann, Werner (Heidelberg, Max Planck Inst.)
The LHCb measurements of the $\mu / e$ ratio in $B \to K \ell \ell$ decays $(R_{K^{}})$ indicate a deficit with respect to the Standard Model prediction, supporting earlier hints of lepton universality violation observed in the $R_{K^{(*)}}$ ratio. Possible explanations of these $B$-physics anomalies include heavy $Z'$ bosons or scalar and vector leptoquarks mediating $b \to s \mu^+ \mu^- $. [...]

Towards a Muon Collider / Accettura, Carlotta (CERN) ; Adams, Dean (Rutherford) ; Agarwal, Rohit (UC, Berkeley (main)) ; Ahdida, Claudia (CERN) ; Aimè, Chiara (Pavia U. ; INFN, Pavia) ; Amapane, Nicola (INFN, Turin ; Turin U.) ; Amorim, David (CERN) ; Andreetto, Paolo (INFN, Padua) ; Anulli, Fabio (INFN, Rome) ; Appleby, Robert (Manchester U.) et al.
A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre of mass energy are being investigated by the recently-formed International Muon Collider Collaboration. [...]

The physics case of a 3 TeV muon collider stage / Muon Collider Collaboration
In the path towards a muon collider with center of mass energy of 10 TeV or more, a stage at 3 TeV emerges as an appealing option. [...]

Has AMS-02 Observed Two-Component Dark Matter? / Profumo, Stefano (UC, Santa Cruz) ; Queiroz, Farinaldo (IIP, Brazil) ; Siqueira, Clarissa (IIP, Brazil)
There is convincing observational evidence for an increasing cosmic-ray positron-to-electron ratio at energies larger than $\sim 10$~GeV, at odds with expectations from secondary positron production. The most recent AMS-02 data exhibit an interesting spectral feature consisting of a bump at an energy around $300$~GeV followed by a drop around $\sim 800$~GeV. [...]

Rare kaon decay to missing energy: Implications of the NA62 result for a $Z′$ model / de Melo, Téssio B. (Rio Grande do Norte U.) ; Kovalenko, Sergey (Andres Bello Natl. U.) ; Queiroz, Farinaldo S. (Rio Grande do Norte U.) ; Siqueira, C. (Rio Grande do Norte U.) ; Villamizar, Yoxara S. (Rio Grande do Norte U.)
Meson decays offer a good opportunity to probe new physics. The rare kaon decay $K^+ \rightarrow \pi^+ \nu\bar{\nu}$ is one of the cleanest of them and, for this reason, is rather sensitive to new physics, in particular, vector mediators. [...]

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.

Collider Bounds on 2-Higgs Doublet Models with $U(1)_X$ Gauge Symmetries / Camargo, Daniel A. (Rio Grande do Norte U.) ; Delle Rose, Luigi (INFN, Florence ; Florence U.) ; Moretti, Stefano (Southampton U. ; CERN ; Rutherford ; Southampton U.) ; Queiroz, Farinaldo S. (Rio Grande do Norte U. ; Rio Grande do Norte U.)
2-Higgs Doublet Models (2HDMs) typically need to invoke an ad-hoc discrete symmetry to avoid severe flavor bounds and in addition feature massless neutrinos, thus falling short of naturally complying with existing data. [...]
