ALP-Pions generalized
Triparno Bandyopadhyay, Subhajit Ghosh, Tuhin S. Roy
A light axion-like particle or an ALP not just gives rise to interesting and spectacular signals of new physics as final states in meson decays, it necessarily leaves tell-tale sig…
Muon and Electron Anomalies with Non-Holomorphic Interactions in MSSM
Md. Isha Ali, Manimala Chakraborti, Utpal Chattopadhyay +1
The recent Fermilab muon result and the same for electron due to fine-structure constant measurement through matter-wave interferometry are probed in relat…
Large Energy Singles at JUNO from Atmospheric Neutrinos and Dark Matter
Bhavesh Chauhan, Basudeb Dasgupta, Amol Dighe
Large liquid scintillator detectors, such as JUNO, present a new opportunity to study neutral current events from the low-energy end of the atmospheric neutrinos, and possible new…
Neutrino propagation when mass eigenstates and decay eigenstates mismatch
Dibya S. Chattopadhyay, Kaustav Chakraborty, Amol Dighe +2
We point out that the Hermitian and anti-Hermitian components of the effective Hamiltonian for decaying neutrinos cannot be simultaneously diagonalized by unitary transformations f…
Constraints on ultralight axions, vector gauge bosons, and unparticles from geodetic and frame-dragging measurements
Tanmay Kumar Poddar
The geodetic and frame-dragging effects are the direct consequences of the spacetime curvature near Earth which can be probed from the Gravity probe B (GP-B) satellite. The satelli…
Phenomenological analysis of multi-pseudoscalar mediated dark matter models
Shankha Banerjee, Geneviève Bélanger, Disha Bhatia +2
Non-minimal simplified extensions of the Standard Model have gained considerable currency in the context of dark matter searches at the LHC, since they predict enhanced mono-Higgs…
Collective Neutrino Flavor Instability Requires a Crossing
Basudeb Dasgupta
Neutrinos in supernovae, neutron stars, and in the early Universe may change flavor collectively and unstably, due to neutrino-neutrino forward-scattering. We prove that for collec…
Frugal models with non-minimal flavor violation for anomalies and neutrino mixing
Disha Bhatia, Nishita Desai, Amol Dighe
We analyze the class of models with an extra gauge symmetry that can account for the anomalies by modifying the Wilson coefficients and $C_{9μ…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…
Use of polarization in to measure the triple-Higgs coupling
Kumar Rao, Saurabh D. Rindani, Priyanka Sarmah +1
It is shown that a certain angular asymmetry of charged leptons produced in the decay of in the process , related to a tensor polarization component of the ,…
Majorana Neutrinos, Exceptional Jordan Algebra, and Mass Ratios for Charged Fermions
Vivan Bhatt, Rajrupa Mondal, Vatsalya Vaibhav +1
We provide theoretical evidence that the neutrino is a Majorana fermion. This evidence comes from assuming that the standard model and beyond-standard-model physics can be describe…
Leptonic Operators for Cabbibo Angle Anomaly with SMEFT RG Evolution
Ashutosh Kumar Alok, Amol Dighe, Shireen Gangal +1
The measurements of the Cabibbo--Kobayashi--Maskawa (CKM) elements can be contaminated by new-physics effects. We point out that purely leptonic operators at the high scale can inf…
Left-Right symmetric fermions and sterile neutrinos from complex split biquaternions and bioctonions
Vatsalya Vaibhav, Tejinder P. Singh
In this article we investigate the application of complex split biquaternions and bioctonions to the standard model. We show that the Clifford algebras Cl(3) and Cl(7) can be used…
On non-conformal kinetic theory and hydrodynamics for Bjorken flow
Sunil Jaiswal, Chandrodoy Chattopadhyay, Lipei Du +2
Using and comparing kinetic theory and second-order Chapman-Enskog hydrodynamics, we study the non-conformal dynamics of a system undergoing Bjorken expansion. We use the concept o…
Sterile Neutrinos
Basudeb Dasgupta, Joachim Kopp
Neutrinos, being the only fermions in the Standard Model of Particle Physics that do not possess electromagnetic or color charges, have the unique opportunity to communicate with f…
A deuterated liquid scintillator for supernova neutrino detection
Bhavesh Chauhan, Basudeb Dasgupta, Vivek Datar
For the next galactic supernova, operational neutrino telescopes will measure the neutrino flux several hours before their optical counterparts. Existing detectors, relying mostly…
Di-Higgs production () in Composite Models
A. Bharucha, G. Cacciapaglia, A. Deandrea +4
In Standard Model (SM) Higgs Boson pair production initiated by photons () is loop-generated process and thereby very sensitive to any new couplings and particles that m…
Is the Chiral Magnetic Effect fast enough?
Jewel K. Ghosh, Sebastian Grieninger, Karl Landsteiner +1
It depends: While we find within holography that the lifetime of the magnetic field for collider energies like the ones achieved at RHIC is long enough to build up the chiral magne…
Constraining electroweak and strongly charged long-lived particles with CheckMATE
Nishita Desai, Florian Domingo, Jong Soo Kim +4
Long-lived particles have become a new frontier in the exploration of physics beyond the Standard Model. In this paper, we present the implementation of four types of long-lived pa…
The role of symmetry breaking in the QCD corrections to the pion mass difference
Mahammad Sabir Ali, Chowdhury Aminul Islam, Rishi Sharma
The charged and neutral pion mass difference can be attributed to both the QED and QCD contributions. The current quark mass difference () is the source of the QCD contribution…
Effect of magnetic field on jet transport coefficient
Debjani Banerjee, Prottoy Das, Souvik Paul +4
We report the estimation of jet transport coefficient, for quark- and gluon-initiated jets using a simple quasi-particle model in absence and presence of magnetic field.…
Probing mild-tempered neutralino dark matter through top-squark production at the LHC
Monoranjan Guchait, Arnab Roy, Seema Sharma
The lightest neutralino, assumed to be the lightest supersymmetric particle, is proposed to be a dark matter (DM) candidate for the mass (100) GeV. Constraints from variou…
Quarkonium propagation in the quark gluon plasma
Rishi Sharma
In relativistic heavy ion collisions at RHIC and the LHC, a quark gluon plasma (QGP) is created for a short duration of about 10fm/c. Quarkonia (bound states of and $b\b…
Fast Flavor Oscillations of Astrophysical Neutrinos with Crossings
Soumya Bhattacharyya, Basudeb Dasgupta
In the early Universe, as well as in supernovae and merging neutron stars, neutrinos have such high densities that they affect each other and exhibit collective flavor oscillations…
