Impact of Primordial Black Holes Induced Neutrinos on the Cosmic 21-cm Brightness Temperature
Prabhav Singh, Mansi Dhuria, Gaurav Goswami
We study the impact of neutrinos emitted from evaporating Primordial Black Holes (PBHs) on the global 21-cm absorption signal during the dark ages and pre-reionization epochs. PBHs…
KM3-230213A and IceCube Neutrino Events from Metastable Dark Matter of Primordial Black Hole Origin
Prabhav Singh, Mansi Dhuria, Nathanael Varghese Job
We investigate a scenario in which the recently observed ultra-high-energy neutrino event KM3-230213A, with a median energy of approximately 220 PeV, as well as the high-energy neu…
Probing self-interacting ultrahigh-energy neutrinos with the cosmic 21-cm signal
Mansi Dhuria, Bishnu Gupta Teli
In this study, we investigate the constraints on secret self-interactions of neutrinos by examining the impact of radiative scattering of ultrahigh-energy neutrinos. These neutrino…
GRB221009A gamma-ray events from non-standard neutrino self-interactions
Mansi Dhuria
The flux of high-energy astrophysical neutrinos observed by the present generation of neutrino detectors has already indicated a few hints of new physics beyond the Standard Model.…
Synergy Between Hubble Tension Motivated Self-Interacting Neutrino and KeV-Sterile Neutrino Dark Matter
Mansi Dhuria, Abinas Pradhan
The discrepancy between the value of Hubble constant measured by CMB observations and local low-redshift based observations has proposed many solutions which require the existence…
A strong broadband 21 cm cosmological signal from dark matter spin-flip interactions
Mansi Dhuria, Viraj Karambelkar, Vikram Rentala +1
In the standard cosmology, it is believed that there are two relatively weak and distinct band-limited absorption features, with the first absorption minima near 20 MHz ()…
Extracting the effective contact rate of COVID-19 pandemic
Gaurav Goswami, Jayanti Prasad, Mansi Dhuria
In the absence of any available vaccines or drugs, prevention of the spread of Coronavirus Disease 2019 (COVID-19) pandemic is being achieved by putting many mitigation measures in…
Trans-Planckian Censorship Conjecture and Non-thermal post-inflationary history
Mansi Dhuria, Gaurav Goswami
The recently proposed Trans-Planckian Censorship Conjecture (TCC) can be used to constrain the energy scale of inflation. The conclusions however depend on the assumptions about po…
Cosmology in the presence of multiple light moduli
Bobby S. Acharya, Mansi Dhuria, Diptimoy Ghosh +2
The generic expectation in string/supergravity models is that there are multiple moduli fields with masses of the order of the supersymmetry breaking scale. We study the cosmology…
Anomalous EDGES 21-cm Signal and Moduli Dominated Era
Mansi Dhuria
The EDGES collaboration has recently reported the detection of an unexpectedly stronger absorption signal in the global 21-cm spectrum around cosmic red-shift z = 17, resulting in…
PeV scale Supersymmetry breaking and the IceCube neutrino flux
Mansi Dhuria, Vikram Rentala
The observation of very high energy neutrino events at IceCube has grasped a lot of attention in the fields of both astrophysics and particle physics. It has been speculated that t…
Extranatural Inflation Redux
Mansi Dhuria, Gaurav Goswami, Jayanti Prasad
The success of a given inflationary model crucially depends upon two features: its predictions for observables such as those of the Cosmic Microwave background (CMB) and its insens…
Perturbativity, vacuum stability and inflation in the light of 750 GeV diphoton excess
Mansi Dhuria, Gaurav Goswami
The recent observation of the 750 GeV diphoton excess at 13 TeV LHC has motivated many scenarios of physics beyond the Standard Model. In this work, we begin by showing that many m…
Moduli induced cogenesis of baryon asymmetry and dark matter
Mansi Dhuria, Chandan Hati, Utpal Sarkar
We study a cogenesis mechanism in which the observed baryon asymmetry of the universe and the dark matter abundance can be produced simultaneously at low reheating temperature with…

We study the superstring inspired model motivated extension of the supersymmetric standard model to explore the possibility of explaining the recent excess CMS e…
The Excess Signal at the LHC and Constraints on Leptogenesis
Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1
We review the non-supersymmetric (Extended) Left-Right Symmetric Models (LRSM) and low energy -based models to investigate if they can explain both the recently detected exces…
Falsifying leptogenesis for a TeV scale at the LHC
Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1
We point out that the discovery of a right-handed charged gauge boson with mass of around a few TeV, for example through a signal of two leptons and two jets that has bee…
Explaining the CMS and excess and leptogenesis in superstring inspired models
Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1
We show that superstring inspired models can explain both the recently detected excess and signals at CMS, and also allow for leptogenesis.…
